Using a Linux only package in Windows #rstats

Here is some R code for using a R package that has only a tar.gz file available (used to load R packages in Linux) and no Zip file available (used to load R packages in Windows).

Step 1- Download the tar.gz file.

Step 2 Unzip it (twice) using 7zip

Step 3 Change the path variable below to your unzipped, downloaded location for the R sub folder within the package folder .

Step 4 Copy and Paste this in R

Step 5 Start using the R package in Windows (where 75% of the money and clients and businesses still are)

Caveat Emptor- No X Dependencies (ok!)

path="C:\\Users\\KUs\\Desktop\\segue\\R"
b=dir(path)
c=length(b)
for (i in 1:c){source(gsub(" ","",paste(path,"\\",b[i])))}
ls()

Running R and RStudio Server on Red Hat Linux RHEL #rstats

Installing R

  • sudo rpm -ivh http://dl.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm

(OR sudo rpm -ivh http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm )

THEN

  • sudo yum install R

THEN

  • sudo R

(and to paste in Linux Window- just use Shift + Insert)

To Install RStudio (from http://www.rstudio.com/ide/download/server)

32-bit

  •  wget http://download2.rstudio.org/rstudio-server-0.97.320-i686.rpm
  •  sudo yum install --nogpgcheck rstudio-server-0.97.320-i686.rpm

OR 64-bit

  •  wget http://download2.rstudio.org/rstudio-server-0.97.320-x86_64.rpm
  •  sudo yum install --nogpgcheck rstudio-server-0.97.320-x86_64.rpm

Then

  • sudo rstudio-server verify-installation

Changing Firewalls in your RHEL

-Change to Root

  • sudo bash

-Change directory

  • cd etc/sysconfig

-Read Iptables ( or firewalls file)

  • vi iptables

( to quite vi , press escape, then colon :  then q )

-Change Iptables to open port 8787

  • /sbin/iptables -A INPUT -p tcp --dport 8787 -j ACCEPT

Add new user name (here newuser1)

  • sudo useradd newuser1

Change password in new user name

  • sudo passwd newuser1

Now just login to IPADDRESS:8787 with user name and password above

Modifying Sources File in Linux for Monet DB Installation

If you like me are a Linux newbie, the following helps in modifying the source file . i.e for adding in sources for Monet DB installation

sudo sh -c ‘echo “deb http://dev.monetdb.org/downloads/deb/ precise monetdb” > /etc/apt/sources.list.d/monetdb.list’
sudo sh -c ‘echo “deb-src http://dev.monetdb.org/downloads/deb/ precise monetdb” > /etc/apt/sources.list.d/monetdb.list’

 

ps- I was on Google compute/ Linux

 

Amazon drops prices of Linux AMIs by ~20%

Amazon cloud gets more exciting. We are still waiting for the Oracle and Google public clouds (compute) to open up out of beta! See their (rather cluttered) blog

http://aws.typepad.com/aws/2012/10/new-ec2-second-generation-standard-instances-and-price-reductions-1.html

—

Today, we are excited to announce a new generation of the original Amazon EC2 instance family. Second generation Standard instances (M3 instances) provide customers with the same balanced set of CPU and memory resources as first generation Standard instances (M1 instances) while providing customers with 50% more computational capability/core.

M3 instances are currently available in two instance types; extra-large (m3.xlarge) and double extra-large (m3.2xlarge). Examples of applications that can benefit from the additional CPU horsepower of these new instances include media encoding, batch processing, web servers, caching fleets, and many others. Currently, M3 instances are available in the US East (N. Virginia) Region starting at a Linux On-Demand price of $0.58/hr for extra-large instances. Customers can also purchase M3 instances as Reserved Instances or as Spot instances. We will introduce M3 instances in additional regions in the coming months.

To learn more about Amazon EC2 instance types and to find out which instance type might be useful for you, please visit the Amazon EC2 Instance type page.

Pricing Change for M1 Standard Instances
Along with the introduction of the M3 Standard instance family, we are announcing a reduction in Linux On-Demand pricing for M1 Standard instances in the US East (N. Virginia) and US West (Oregon) Regions by almost 19%. The new pricing is effective from November 1 and is described in the following table

Instance Type Previous Price New Price
m1.small $0.080 $0.065
m1.medium $0.160 $0.130
m1.large $0.320 $0.260
m1.xlarge $0.640 $0.520

You can find out more about pricing for all Amazon EC2 instances by visiting the Amazon EC2 pricing page.

so training costs differently different strokes for different folks I guess,

BUT me hearties.

Cost of 1 year of Revolution Enterprise= $1000

Thats a flat rate, so the Linux and Windows costs the same and so does the 32-bit and 64-bit

(see http://buy.revolutionanalytics.com/ )

( My comment- either Revo should give away the license for free to enterprises, rationalize training costs, seriously how can 2 days of training cost like a 1 year of license and the software is definitely quite good., or create a paid Amazon Ec 2 AMI for enterprises to rent the Revolution Analytics software (like SAP Hana ), or even on Windows Azure if they insist on hugging Microsoft, though I am clearly seeing various flavors of Linux beating Windows Server to a pulp in the Big Data market, though I am probably more optimistic on the Windows 8 on Surface but because of hardware not software/ Azure alternative to Amazon given Google’s delayed offering- I dont even know many many instance of Windows related HPC or HPA,  (/end_of_rant)

Annual Subscription

R now part of Amazon Linux AMI

Based on this post, Amazon now had decided to bundle R with Amazon Linux AMI

http://aws.typepad.com/aws/2012/10/amazon-linux-ami-201209-now-available.html

R 2.15: Also coming from your requests, we have added the R language to the Amazon Linux AMI.  We are here to serve your statistical analysis needs!  Simply yum install R and off you go.

ps- back to work. sorry for the delayed posts . I am working on book 2 for Springer- “R for Cloud Computing” . If you have any case studies of R on Amazon,Google, Oracle or Azure clouds please let me know.

pps- With 48 mb, is R too big to bundle in the many default Linux distros . Thoughts?

 

Running R on Windows Azure #rstats #cloud

Here is a brief tutorial for people to run R on Windows Azure Cloud (OS=Windows in this case , but there are 4 kinds of Linux also available)

There is a free 90 day trial so you can run R for free on the cloud for free (since Google Cloud Compute is still in closed hush hush beta)
