R Node- and other Web Interfaces to R

vector version of this image — Image via Wikipedia

R Node is a great web interface to R.

http://squirelove.net/r-node/doku.php

Features

Access to a R server backend via a web browser UI
The web browser UI works in all modern browsers, including IE 7 and 8 (excluding SVG based graphs).
Username/password login (both from the browser to the R-Node server, and from the R-Node server to Rserve and R).
- Per-user R sessions. Each user can have their own R workspace, or they can share.
Support for most R commands that perform statistical analysis and provide textual feedback.
Support for most standard R commands that provide graphical feedback via server side generation of the graphs. Some graphs (e.g. plot() can be plotted via SVG client-side as well).
Downloading of generated graphs.
Accessing R help files using help() and ? commands (Note R v2.10 altered how help is provided, so this currently is not working in R v2.10)
Uploading files to work with their data in R.

Many commands will work. Try a command, if it does not work, use the feedback button in the application to let us know.

Limitations

Various R functions are not supported. These include:
- Installation of new R packages.
- Searching of help via ??.
- Example calls (via example()).

An impressive implementation of time series analysis based on R and Javascript. This web server creates separate browser windows for data entry, graphics, and procedure selection. These windows are dynamic. For example, after entering data there is no submit button to submit the data. The procedure selection window is used to start the analysis, which uses the current values in the data window.

Deleting Twitter, Facebook,LinkedIn- Accepting Life

This Thanksgiving as I prayed to God for my family– I prayed to him to give me more time with my loving family. An insight or revelation struck me-

I was spending more time with my computer than with my loved ones.

Is Twitter, Facebook, LinkedIn essential to living? No

I have 1700 followers on Twitter

1100 “Friends” on Facebook, and 9429 “Connections” on Linkedin

Deleting Facebook was an emotionally wrenching decision- see this screenshot- I tried to download all my account- family photos (320 mb) but connection kept breaking-

so I had just deactivate and not delete the account. You win, Zuckenberg

How to-

Right Hand Top Corner —-Account Settings- Deactivate Account

After Facebook de activates your account- it mocks you by saying this this in YELLOW “

Your Facebook account has been deactivated.

To reactivate your account, log in using your old login email and password. You will be able to use the site like you used to.

We hope you come back soon.”

I go back to Facebook to download all my family photos before final deletion (and not just de activation)- I get this message

It may take a little while for us to gather all of your photos, wall posts, messages, and other information. We will then ask you to verify your identity in order to help protect the security of your account.

Yeah Yeah Mark.

One Down Two to Go

Deleting Twitter

Twitter was disappointingly easy-

Go to http://twitter.com/settings/account

At bottom left you see Deactivate my account.

Twitter tries to scare me now-

Is this goodbye?

This action is permanent.

Are you sure you don’t want to reconsider? Was it something we said? Tell us.

Before you deactivate your account, know this:

This action is permanent: account restoration is currently disabled.
You do not need to deactivate your account to change your username. (You can change it on the settings page. All @replies and followers will remain unchanged.)
Your account may be viewable on twitter.com for a few days after deactivation.
We have no control over content indexed by search engines like Google.
If you’re creating a new account and want to use the same user name, phone number and/or email address associated with this account, you must first change them on this account before you deactivate it. If you don’t, the information will be tied to this account and unavailable for use.
Okay, fine, deactivate my account (thats the button)

I clicked the Okay fine Button.

One more pop up-

Re-enter your Twitter password to deactivate @DecisionStats.

Ok Done-

Twitter tries to scare me again —-

You deactivated your account.

Account restoration is currently unavailable. Here is the message you agreed to before deactivating your account:

his action is permanent.

Before you deactivate your account, know this:

This action is permanent: account restoration is currently disabled.
You do not need to deactivate your account to change your username. (You can change it on the settings page. All @replies and followers will remain unchanged.)
Your account may be viewable on twitter.com for a few days after deactivation.
We have no control over content indexed by search engines like Google.
If you’re creating a new account and want to use the same user name, phone number and/or email address associated with this account, you must first change them on this account before you deactivate it. If you don’t, the information will be tied to this account and unavailable for use.

So Long Twitter, I gotta spend more time with my offline family okay.

And probably anyone trying to do sentiment analysis on my twitter feed for social media analytics now has an incomplete data point (hehe)

Last One- Linkedin 9349 connections are valuable- I was thinking of auctioning this on E Bay but they kicked me out.

So I just go for deletion.

I spend 10 minuted looking for the delete account button-this is getting a bit annoying now.

I finally go to

http://help.linkedin.com/

Item 4- Closing my Account-

Linkedin neither scares me nor emotionally coddles me – This is what is says-

Closing Your Account

How do I close my account?

Log into the account you wish to close.
Hover your cursor over your name in the top right of your home page and then click “Settings”.
Click on “Close Your Account” under Personal Information.
Select a reason for closing your account.
Click on “Continue”.

Members should only have one LinkedIn account. Multiple accounts can prevent the ability to accept an Invitation. Closing additional accounts should resolve this dilemma. Prior to closing any secondary accounts:

Inventory all connections and identify any that may be missing from the primary account you wish to keep.
Send Invitations to those connections missing from the primary account.
Update any profile information that maybe on other account profiles.

So I try exporting all 9300 + connections using http://www.linkedin.com/addressBookExport

I dont think I will send that many invites again- but some of these people have been good to me ( 18 of them even wrote recommendations- which are non exportable it seems)

I check my downloaded csv file- yup all 9379 email addresses are there.

Final round-

Update- Linkedin does NOT get deleted. I get this-

Your close account request must be processed by customer support for the following reason:

You have more than 250 connections.

You will receive a confirmation email from customer support indicating that they received your request to close your account.

The account that customer support will process for closure is below:

Ajay Ohri
9,429 Connections
16 Recommendations
ohri2007@gmail.com (primary address)

and the email says

Member Comment: ajay ohri

11/24/2010 23:10

Member ID: 6691344
Member Name: Ajay Ohri

The member has attempted to self close this account and was unable because:

The member has a large network of connections to close. Please close during non peak hours.

Please confirm with the member when his or her account has been successfully closed.

So long people- you know where to find me- on this blog (and some on skype).

And if you dont’ know how to find me on my blog-

Happy Thanksgiving-and kill that Turkey 🙂

Using Firesheep on Campus, Caltrain and beyond

Cookie theft by sniffing on the network — Image via Wikipedia

You must have heard about Firesheep-

it is a simple utility that adds on your Firefox browser– and simply traps all cookies floating around on public wi-fis like airports, university campuses, caltrain and soon san fransisco

Basically White Hat Hacking made easy so you can pose as anyone else on Facebook– if they are logged in nearby

When logging into a website you usually start by submitting your username and password. The server then checks to see if an account matching this information exists and if so, replies back to you with a “cookie” which is used by your browser for all subsequent requests.

It’s extremely common for websites to protect your password by encrypting the initial login, but surprisingly uncommon for websites to encrypt everything else. This leaves the cookie (and the user) vulnerable. HTTP session hijacking (sometimes called “sidejacking“) is when an attacker gets a hold of a user’s cookie, allowing them to do anything the user can do on a particular website. On an open wireless network, cookies are basically shouted through the air, making these attacks extremely easy.

Running R on Amazon EC2 :Windows

Running R on an Amazon EC2 has following benefits-

1) Elastic Memory and Number of Processors for heavy computation
2) Affordable micro instances for smaller datasets (2 cents per hour for Unix to 3 cents per hour).
3) An easy to use interface console for managing datasets as well as processes

Running R on an Amazon EC2 on Windows Instance has following additional benefits-

1) Remote Desktop makes operation of R very easy
2) 64 Bit R can be used
3) You can also use your evaluation of Revolution R Enterprise (which is free to academics) and quite inexpensive for enterprise software for corporates.

You can thus combine R GUIs (like Rattle , R Cmdr or Deducer based upon your need for statistical analysis, data mining or graphical analysis) , with 64 Bit OS, and Revolution’s REvoScaler Package to manage huge huge datasets at a very easy to use analytics solution.

$0.01 per 10,000 GET requests (when loading a snapshot)

http://aws.amazon.com/ec2/#pricing Other costs are optional to your needs

Based on the above- I set out to try and create a how-to DIY for running R (and RevolutionR on 64bit Windows on EC2)

1) Logon to https://console.aws.amazon.com/ec2/home

2) Launch Windows Instance

Choose AMI

Left Margin-AMI-

Top Windows – Select Windows 64 AMI

(note if you select SQL Server it will cost you extra)

Then go through the following steps and launch instance

Selecting EC2 compute depending on number of cores, memory needs and budget

Create a key pair (a .pem file which is basically an encrypted password) and download it.
For tags, etc just click on and pass (or read and create some tags to help you remember, and organize multiple instances)
In configure firewall, remember to Enable Access to RDP (Remote Desktop) and HTTP. You can choose to enable whole internet or your own ip address/es for logging in
Review and launch instance

Go to instance (leftmost margin)

and see status (yellow for pending)
Click on Instance Actions-Connect on Top Bar to see following
Download the .RDP shortcut file and
Click on Instance Actions-Request Admin Password

Wait 15 minutes while burning few cents for free as Microsoft creates a password for you
Have coffee (or tea is you are health minded)
Click Again on Instance Actions-Request Admin Password

Open the key pair file (or .pem file created earlier) using

notepad, and copy and paste the Private Key (looks like gibberish)- and click Decrypt.

Retrieve Password for logging on.

Note the new password generated- this is your Remote Desktop Password.

Click on the .rdp file (or Shortcut file created earlier)- It will connect to your Windows instance.

Enter the new generated password in Remote Desktop

This looks like a new clean machine with just Windows OS installed on it.

Install Chrome (or any other browser) if you do not use Internet Explorer
Install Acrobat Reader (for documentation), Revolution R Enterprise~ 490 mb (it will automatically ask to install the .NET framework-4 files) and /or R

Install packages (I recommend installing R Commander, Rattle and Deducer). Apart from the fact that these GUIs are quite complimentary- they also will install almost all main packages that you need for analysis (as their dependencies) Revolution R installs parallel programming packages by default.

If you want to save your files for working later, you can make a snapshot (go to amazon console-ec2- left margin- ABS -Snapshot- you will see an attached memory (green light)- click on create snapshot to save your files for working later
If you want to use my Windows snapshot you can work on it , just when you start your Amazon Ec2 you can click on snapshots and enter details (see snapshot name below) for making a copy or working on it for exploring either 64 bit R, or multi core cloud computing or just trying out Revolution R’s new packages for academic purposes.

Running a R GUI,and parallel programming on Amazon EC2

Ok here is an update to the post on running R on an Amazon EC2.

https://decisionstats.wordpress.com/2010/09/25/running-r-on-amazon-ec2/

1) Login to Amazon Console using instructions in earlier post

2) Select AMI-Platform Ubuntu-i-5575773f

Basically select the latest 64 bit instance from Ubuntu

3) Proceed as in post before to launch AMI and instance- here I chose large with 4cores

3.1) Before connecting to your session

search Synaptic Package Manager for x11-

I installed the X11 VNC server package –

and now interactive sessions will work (read GUIs)

3.2) Modify the line

ssh -i decisionstats2.pem root@ec2-75-101-182-203.compute-1.amazonaws.com

ssh -i decisionstats2.pem -X ubuntu@ec2-75-101-182-203.compute-1.amazonaws.com

This will connect you.

4) INSTALL R – Cran R is a standard Ubuntu Package

using

sudo apt-get install r-base

then type R

and install.packages(“Rcmdr”)

Note – you should be able to see the grey colored Tcl/Tpk script showing cran locations

in a seperate window if X11 is working

5) doSNOW package works on the Ubuntu 64- The results are below for

check <-function(n) {check <-function(n) {

+ for(i in 1:1000)

+ {

+ sme <- matrix(rnorm(100), 10,10)

+ solve(sme)

+ }

> times <- 100

> system.time(x <- foreach(j=1:times ) %dopar% check(j))
user system elapsed
0.150 0.080 7.303
> system.time(for(j in 1:times ) x <- check(j))
user system elapsed
27.460 2.300 29.757

The time of 7.3 is almost 5.5 times faster than running it locally on a dual core, and still 3 times faster than running foreach locally. Note I used 4 cores this time in snow.

5) The Tcl/Tk interface of R Cmdr takes a long time to load on EC2 than locally. It may be due to the fact I was running Ubuntu using a VM Player (http://www.vmware.com/go/downloadplayer/ ). However there seems to be a general slowing down when viewing graphics.

or simply

sudo apt-get install r-cran-rcmdr

Running R on Amazon EC2

On my second day of bludering about high technology, I came across http://rgrossman.com/2009/05/17/running-r-on-amazons-ec2/ which describes how to run R on Amazon EC2.

I tried it out and have subsequently added some screenshots to this tutorial so as to help you run R. My intention of course was to run a R GUI preferable Revolution Enterprise on the Amazon EC 2- and crunch uhm a lot of data.

Now go through the steps as follows-

0) Logging onto Amazon Console

http://aws.amazon.com/ec2/

Note you need your Amazon Id (even the same id which you use for buying books).

Note we are into Amazon EC2 as shown by the upper tab. Click upper tab to get into the Amazon EC2

2) Choosing the right AMI-

On the left margin, you can click AMI -Images.

Now you can search for the image-

I chose Ubuntu images (linux images are cheaper) and opendata in the search as belows- I get two images.

You can choose whether you want 32 bit or 64 bit image. Thumb rule- 64 bit images are preferable for data intensive tasks.

Click on launch instance in the upper tab ( near the search feature)

2) A pop up comes up, which shows the 5 step process to launch your computing.

Choose the right compute instance- As the screenshot shows- there are various compute instances and they all are at different multiples of prices or compute units.

After choosing the compute instance of your choice (extra large is highlighted)- click on continue-

3) Instance Details-

I did not choose cloudburst monitoring as it has a extra charge- and I am just trying out things.So I simply clicked continue.

4) Add Tag Details- If you are running a lot of instances you need to create your own tags to help you manage them. Advisable if you are running many instances.

Since I am going to run just one- I clicked continue with adding just two things OS and Stats Package.

5) Create a key pair- A key pair is an added layer of encryption. Click on create new pair and name it (note the name will be handy in coming steps)

After clicking and downloading the key pair- you come into security groups. Security groups is just a set of instructions to help keep your data transfer secure. So I created a new security group.

And I added some ways in security group to connect (like SSH using Port 22)

7) Last step- Review Details and Click Launch

8) On the Left margin click on instances ( you were in Images.>AMI earlier)

It will take some 3-5 minutes to launch an instance. You can see status as pending till then.

9) Pending instance as shown by yellow light-

10) Once the instance is running -it is shown by a green light.

Click on the check box, and on upper tab go to instance actions. Click on connect-

you see a popup with instructions like these-

Open the SSH client of your choice (e.g., PuTTY, terminal).

Locate your private key file, decisionstats2.pem

Use chmod to make sure your key file isn’t publicly viewable, ssh won’t work otherwise:
chmod 400 decisionstats.pem

Connect to your instance using instance’s public DNS [ec2-75-101-182-203.compute-1.amazonaws.com].

Example

Enter the following command line:

ssh -i decisionstats2.pem root@ec2-75-101-182-203.compute-1.amazonaws.com

IMPORTANT-

If you are choosing Ubuntu Terminal to connect- you need to change the word root from above to Ubuntu above.

12) To launch R, just type R at the terminal

If all goes well you should be able to see this-

choose to install any custom packages (like

install.packages(‘doSNOW’)

work on R using command line

13) IMPORTANT- After doing your R work, please CLOSE your instance (

Go to LEFT Margin-Instances-Check the check box of instance you are running- on upper tab- Instance Actions- Click Terminate.

2) You can install Revolution R on 32 bit Ubuntu using sudo apt install revolution-r

Various versions of Revolution R are supported on different versions of Linux

see http://www.revolutionanalytics.com/why-revolution-r/which-r-is-right-for-me.php

I may be willing to try Red Hat Enterprise Linux on the ec2 with 64 bit AND Revolution Enterprise to see the maximum juice I can get. or you can try it using an image below- It would be interesting if there could be an Amazon Machine Image for that (paid-public and private-academic)

AMI ID: ami-8ba347e2
Name:–
Description:–
Source:redhat-cloud/RHEL-5-Server/5.2/x86_64/Beta-2.6.18-92.1.1/RHEL5.2-Server-x86_64-Beta-2.6.18-92.1.1.manifest.xml
Owner:432018295444	Visibility:Public	Product Code:54DBF944
State:available	Kernel ID:aki-89a347e0	RAM Disk ID:ari-88a347e1
Image Type:machine	Architecture:x86_64	Platform:Red Hat
Root Device Type:instance-store	Root Device:–	Image Size:0 bytes
Block Devices:N/A – Instance Store
Virtualization:paravirtual

3) My ultimate goal is to run a parallel session using all cores on an EC2 instance and a R GUI (like R Commander or Rattle)

4) For sake of running a test- I re did the parallel test I did on my 2 core laptop

but using 68.4 gb Memory and 8 cores (26 Compute Units brrr)

> check <-function(n) {

+ for(i in 1:1000)

+ {

+ sme <- matrix(rnorm(100), 10,10)

+ solve(sme)

+ }

> times <- 100

> system.time(for(j in 1:times ) x <- check(j))

user system elapsed

20.51 0.00 20.66

Note I still got a faster response than using parallel processors (on a 2 core 3 gb memory) BUT the gain was not as much had I tried to use foreach for running each of the 8 cores parallely. Or running multicore package as in http://www.cerebralmastication.com/2010/02/using-the-r-multicore-package-in-linux-with-wild-and-passionate-abandon/

5) For some reason on Ubuntu 64 bit Amazon image -I cant get Revolution R (even after using sudo apt) , and I am still learning how I can try and get Enterprise Edition fired up on a 64 bit Red Hat Enterprise Linux Amazon AMI (and maybe create an all new Machine Image 😉

6) I was also unable to use the -X command desite having x 11 as in http://rgrossman.com/2009/05/17/running-r-on-amazons-ec2/ so was not able to see graphics,

Also it prevents me from loogin onto as root, and asks me to login as ubuntu@amazon…. I also wanted to try logging into using my Windows session but kept shuttling between my VM Player Ubuntu session and Windows

7) Hope this was useful. I am thankful to tips from Revolution Blog, R Grossman’s Blog, Creators of the Open Data AMI, Tal’s R Statistics Blog and Cerebral Mastication blog on this
