Data Visualization for R packages at Github #rstats

I noticed this article sometime back by the most excellent hacker, John Myles White ( author Machine learning for Hackers)

http://www.johnmyleswhite.com/notebook/2012/08/12/the-social-dynamics-of-the-r-core-team/

Professor John Fox, whom we have interviewed here as the creator of R Commander, talked on this at  User 2008 http://www.statistik.uni-dortmund.de/useR-2008/slides/Fox.pdf

I also noticed that R Project is stuck on SVN ( yes or no??, comment please) while some part of the rest of the World has moved on to Git. See http://en.wikipedia.org/wiki/Git_%28software%29

Is Git really that good compared to SVN http://stackoverflow.com/questions/871/why-is-git-better-than-subversion

Maybe, I think with 5000 packages and more , R -project needs to have more presence on Github and atleast consider Git for the distributed and international project R is becoming.

The second meetup for R New Delhi Users

The R Users of New Delhi met for the second time on Dec 15, 2012. We meet on the third Saturday of every month.

12121

We talked on epidemiology using epi calc package  ( we have 1 doctor and 1 bio statistician) , and Cloud Computing ( we have two IT guys) and Business Analytics. We also discussed the GUI , R Commander , Rattle, and Deducer for beginners and people transitioning to R from other analytics software. We also discussed the R for SAS and SPSS Users books, and R for Data Mining Book. The free book for R for Epidemiology ( http://cran.r-project.org/doc/contrib/Epicalc_Book.pdf ) was mentioned . Not bad for 1 hour.

We are currently unfunded and unsponsored , I hope to get some sponsors to give away R books to encourage users and group members (excluding my own). The only catch to join this meetup group, you either need to attend (and be local) or present something ( if you are not in Delhi)2

I have been trying to get this group to go from Vector to Matrix to get a bigger sponsorship from Revolution , but I am constrained by meeting in a public cafe. That is due to change since we managed to get one sponsor for meeting place in Noida ( a Business School batchmate who owns his office)

Deadlines for applications are:

  • March 31, 2013 for Matrix and Array level groups.
  • September 30, 2013 for Vector level groups.

2013 Sponsorship Levels

The size of the annual grant depends on the size of your group.

Level For groups that are:  Requirements Annual Grant ($USD)
Vector Just getting started A group name, group webpage, and a focus on R. (Here are some tips on starting up a new R user group.) $100
Matrix Smaller but established 3 meetings in last 6 months with 30 attendees or more.  $500
Array Larger and groups  3 meetings in last 6 months with 60 attendees or more. $1000

 

Interviews and Reviews: More R #rstats

I got interviewed on moving on from Excel to R in Human Resources (HR) here at http://www.hrtecheurope.com/blog/?p=5345

“There is a lot of data out there and it’s stored in different formats. Spreadsheets have their uses but they’re limited in what they can do. The spreadsheet is bad when getting over 5000 or 10000 rows – it slows down. It’s just not designed for that. It was designed for much higher levels of interaction.

In the business world we really don’t need to know every row of data, we need to summarise it, we need to visualise it and put it into a powerpoint to show to colleagues or clients.”

And a more recent interview with my fellow IIML mate, and editor at Analytics India Magazine

http://analyticsindiamag.com/interview-ajay-ohri-author-r-for-business-analytics/

AIM: Which R packages do you use the most and which ones are your favorites?

AO: I use R Commander and Rattle a lot, and I use the dependent packages. I use car for regression, and forecast for time series, and many packages for specific graphs. I have not mastered ggplot though but I do use it sometimes. Overall I am waiting for Hadley Wickham to come up with an updated book to his ecosystem of packages as they are very formidable, completely comprehensive and easy to use in my opinion, so much I can get by the occasional copy and paste code.

 

A surprising review at R- Bloggers.com /Intelligent Trading

http://intelligenttradingtech.blogspot.in/2012/10/book-review-r-for-business-analytics.html

The good news is that many of the large companies do not view R as a threat, but as a beneficial tool to assist their own software capabilities.

After assisting and helping R users navigate through the dense forest of various GUI interface choices (in order to get R up and running), Mr. Ohri continues to handhold users through step by step approaches (with detailed screen captures) to run R from various simple to more advanced platforms (e.g. CLOUD, EC2) in order to gather, explore, and process data, with detailed illustrations on how to use R’s powerful graphing capabilities on the back-end.
