The talented Dirk Eddelbuettel has just announced that his new book is coming out this year. I would recommend this book for anyone trying to use R for analytics, Big Data or customized use cases especially if they have a need to speed up the computation times. Rcpp can speed up R by a huge magnitude, and thats because C++ comes closer to the metal.
If you are a business analyst who knows a bit of R, but always were intimidated by C++ programming, well this is the right how to do book for you.
So I finally got my test plan accepted for a 1 month trial to the Oracle Public Cloud at https://cloud.oracle.com/ .
Some initial thoughts- this Java cloud seemed more suitable for web apps, than for data science ( but I have to spend much more time on this).
I really liked the help and documentation and tutorials, Oracle has invested a lot in it to make it friendly to enterprise users.
Hopefully the Oracle R Enterprise ORE guys can talk to the Oracle Cloud department and get some common use case projects going.
In the meantime, I did a roundup on all R -Java projects.
They include- (more…)
Ajay- Describe how you started using R. What are some of the benefits you noticed on moving to R?
Jeff- I began using R in an internship while working on my undergraduate degree. I was provided with some unformatted R code and asked to modularize the code then wrap it up into an R package for distribution alongside a publication.
To be honest, as a Computer Science student with training more heavily emphasizing the big high-level languages, R took some getting used to for me. It wasn’t until after I concluded that initial project and began using R to do my own data analysis that I began to realize its potential and value. It was the first scripting language which really made interactive use appealing to me — the experience of exploring a dataset in R was unlike anything (more…)
We continued the 3 rd month without a sponsor for the R User Meetup group. I wish analytics companies in Gurgaon and Mumbai or even Hyderabad can help sponsor R users meetups, as we need to have more knowledge sharing culture here.
I am a bit disappointed by people who RSVP yes, but cancel out without letting us know.
Some additional insights-
1) Never hold meetup on cricket match day
2) location should be very close to Metro Station.
3) Saturdays will be the only meetup day for future. If I am unavailable, Dr Amir will be leading the Meetup.
Some more action points-
1) Ajay and Dr Amir to work together on a blog / site called R for Medical Researchers focused on Indian issues.
2) For Web Application developers, please see shiny package. I have written on the latest version of Shiny- but I would also like you to click on each of the 18 links I have written in this article. Shiny is great for statistically enabling web apps.
3) We will be uploading files and creating a slideshare for Delhi R Users. This will be our digital archive.
4) To start using R immediately use Rattle ( http://rattle.togaware.com/) especially if you build models or need to use data mining
5) To start using R for GIS and Spatial use Deducer with Spatial Plot Builder Plugin
6) To integrate R with C++ see the RCPP gallery with almost 100 plus packages dependent on it. This will be needed with Developers who are trying to use a faster version of R by using C++ . http://gallery.rcpp.org/
7) Web Analytics using R- is now updated for changes in Google APIs. http://decisionstats.com/2013/01/28/google-analytics-using-rstats-updated/

9) For a beginner in R use http://tryr.codeschool.com
Minutes of Meeting -courtesy Dr Amir
four people (Ajay, myself, Ashish and Nagesh) joined for the 3rd meetup today at around 4 pm at hauz khas village. Ashish and Nagesh are two new members who attended the meetup for the first time. Ashish is in web development with knowledge of python and perl. today he introduced the group about data scraping from web using Perl. Nagesh has a background in management and currently working with insurance company. he is planning to switch to R as it is free. he currently uses SAS. Ajay introduced GUIs like Rattle, Deducer; books (R for business analytics which he himself has authored and others like R for spss and sas users, data mining with r, rattle) and GADM for mapping. I introduced Coursera courses which is currently ongoing and which uses R and also the basics of R like packages, functions and strengths of R.Ashish has volunteered to find a place for meetup in Green Park near the metro station as we are still struggling to get a decent place for our meetups.
Also – here is the meetup group for New Delhi R Users
Due to changes in Google APIs my earlier post on using Google Analytics in R is deprecated. Unfortunately it is still on top 10 results for Google results for Using Google Analytics with R.
That post is here http://decisionstats.com/2012/03/20/using-google-analytics-with-r/
A more updated R package on Google Analytics and R is here . https://github.com/skardhamar/rga
A better updated post on an easy to use tutorial on using Google Analytics with R using OAuth 2 playground is here.
- Set the Google analytics query parameters for preparing the request URI
- Get the access token from Oauth 2.0 Playground
- Retrieve and select the Profile
- Retrieving GA data
Note it is excellent for learning to use RJSON method as well. You can see the details on the Tatvic blog above.
