httR by Hadley #rstats

The awesome Hadley Wickham has just released the next version of httr package. Prof Hadley is currently on leave from Rice Univ and working with the tremendous geeks at R Studio . New things in the httr package-

 

http://blog.rstudio.org/2012/10/14/httr-0-2/

httr, a package designed to make it easy to work with web APIs. Httr is a wrapper around RCurl, and provides:

  • functions for the most important http verbs: GET, HEAD, PATCH, PUT, DELETE and POST.
  • support for OAuth 1.0 and 2.0. Use oauth1.0_token and oauth2.0_token to get user tokens, and sign_oauth1.0 and sign_oauth2.0to sign requests. The demos directory has six demos of using OAuth: three for 1.0 (linkedin, twitter and vimeo) and three for 2.0 (facebook, github, google).

I especially like the OAuth functionality as I occasionaly got flummoxed with existing R OAuth packages , and this should hopefully lead to awesome new social media analytics posts by the larger R blogger community. Also given the fact that unauthenticated API requests to Twitter are greatly expanded by OAuth authenticated requests- (see https://dev.twitter.com/docs/rate-limiting )

  • Unauthenticated calls are permitted 150 requests per hour. Unauthenticated calls are measured against the public facing IP of the server or device making the request.
  • OAuth calls are permitted 350 requests per hour and are measured against the oauth_token used in the request.

 

some creative use cases should see an incredible amount of cross social media analysis (not just one social media channel ) at a time.

R for Social Media Analytics ? Watch this space.. 😉

Online Education- MongoDB and Oracle R Enterprise

I really liked the course developed by 10 gen for MongoDB (there are two tracks for Developers and DBAs at https://education.10gen.com/)

The interface is very nice and is a step upwards from Coursera’s ( https://www.coursera.org/) pioneering work (and even http://www.codecademy.com/#!/exercises/0 )– each video has a small question, the videos are not cluttered, and the voice and transcription quality is impeccable. Lastly a certification for people who clear 65% acts as an academic incentive, they get a certificate.

yes it is free.

 

Oracle recently launched a series of nicely made R tutorials at https://apex.oracle.com/pls/apex/f?p=44785:24:0::NO::P24_CONTENT_ID,P24_PREV_PAGE:6528,1but I wish Oracle R had some certifications too!

If only more techie companies like SAS Institute (expensive SAS training), IBM (cluttered website), Revolution Analytics (expensive partners in Certification), Google (unpolished Python lectures)

put an effort with polished e-learning interfaces than be dependent on external partners…..or internal gurus…interfaces matter especially in education.

\Well Anyways!!

Happy Mongo DBing/ Oracle R!

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?
