Learning and Teaching R #rstats
a brief ppt I made for the New Delhi Meetup Group http://www.meetup.com/New-Delhi-R-UseR-Group/
Cloud versions of Latex
I work with Lyx http://www.lyx.org/, the GUI for Latex http://en.wikipedia.org/wiki/LaTeX, for writing my books. 18 years of writing in MS Word, and yes I have rightly criticized for my bad formatting. I hope to do a better job for R for Cloud Computing. Someday I will learn Latex and Sweave http://www.stat.uni-muenchen.de/~leisch/Sweave/ as well (sighs)
Sweave is a tool that allows to embed the R code for complete data analyses in latex documents. The purpose is to create dynamic reports, which can be updated automatically if data or analysis change. Instead of inserting a prefabricated graph or table into the report, the master document contains the R code necessary to obtain it. When run through R, all data analysis output (tables, graphs, etc.) is created on the fly and inserted into a final latex document. The report can be automatically updated if data or analysis change, which allows for truly reproducible research.
Where can I get it?
The Sweave software itself is part of every R installation
But alternatives to Lyx for a browser only version of Latex do exist.
There are two three of them right now
1) https://www.sharelatex.com/ ShareLaTeX is now open source! ShareLaTeX is an online real-time collaborative LaTeX editor, and you can now run your own local version where you can host, edit, collaborate in real-time, and compile your LaTeX documents. You can run the hosted version at http://www.sharelatex.com,
2) http://fiduswriter.org/ Fidus Writer is an online collaborative editor especially made for academics who need to use citations and/or formulas. The editor focuses on the content rather than the layout, so that with the same text, you can later on publish it in multiple ways: On a website, as a printed book, or as an ebook. In each case, you can choose from a number of layouts that are adequate for the medium of choice.
3) https://www.writelatex.com/
All are equally good and equally nascent. I like that Writelatex has an API
I like the Fidus Writer interface more but the ShareLatex has a bigger set of templates. I think Write Latex is more evolved than Fidus Writer but will still need to catch up with Share Latex
Both are available on Github for tinkering.
https://github.com/fiduswriter/fiduswriter and
https://github.com/sharelatex/sharelatex and
https://github.com/sweenzor/writelatex-compile
Maybe I will have to wait for Google Docs for creating an application for Latex typesetting. In the meantime, we shall Lyx.
(Hat tip – S Boucher for pointing me to write latex)
Price of Analytics Education from Indian Service Providers
This is an unedited list of education providers from India, with both classroom and online trainings. 1$ =55Rs. The list will be updated as and when changes occur or when a reader suggests. I will only be putting prices that can be referenced via a URL. Also later I will try and create an index to track prices. Because I have had relationships with a lot of people in Indian Analytics- I will try and put this in a Google Docs spreadsheet.
The basic template will be

Brewer’s CAP Theorm
CAP theorem states that there are three basic requirements which exist in a special relation when designing applications for a distributed architecture.
Consistency – This means that the data in the database remains consistent after the execution of an operation. For example after an update operation all clients see the same data.
Availability – This means that the system is always on (service guarantee availability), no downtime.
Partition Tolerance – This means that the system continues to function even the communication among the servers is unreliable, i.e. the servers may be partitioned into multiple groups that cannot communicate with one another.
In theoretically it is impossible to fulfill all 3 requirements. CAP provides the basic requirements for a distributed system to follow 2 of the 3 requirements. Therefore all the current NoSQL database follow the different combinations of the C, A, P from the CAP theorem. Here is the brief description of three combinations CA, CP, AP :
CA – Single site cluster, therefore all nodes are always in contact. When a partition occurs, the system blocks.
CP – Some data may not be accessible, but the rest is still consistent/accurate.
AP – System is still available under partitioning, but some of the data returned may be inaccurate.

SAS makes it free to learn SAS
Wanna learn SAS language? Why go elsewhere? Get the original software in a virtual machine from the guys who actually created it!
http://www.sas.com/en_us/offers/14q1/122603-sas-for-academia/overview.html
It’s a 2 1.4 GB download and does require a 2 minute registration but thats all. You can even protype in it before you take that all important call to go for which software to buy for your analytics need. Note – retraining existing SAS analysts in R is expensive in terms of training costs, business disruption and code migration. Now only if someone could create a software to change SAS code into R code – that would make things different !!
SAS language analysts continue to be in much more demand than R language analysts- partly due to the failure of an authentic official R certification as it does not exist ( a fact that has been exploited by various institutes that teach you language syntax but not the analytics) and the poor state of the mothership R website with its huge and sometimes over detailed documentation
https://communities.sas.com/community/sas-analytics-u
and I really like the professionalism as well as the generosity of the institute. Someone famous once predicted SAS will disappear by 2015 ( based on a time series model ). With billions of dollars and it’s kitty and decade long shrewd and street smart management, SAS is going to stay up a wee bit longer and give it’s wannabe killers a bloody nose or two.
Thank you Professor Goodnight
