success 3926 R 2007-01-04T16:37:11Z 2009-11-22T00:45:46Z R is a language and environment for statistical computing and graphics. It is a GNU project which is similar to the S language and environment which was developed at Bell Laboratories (formerly AT&T, now Lucent Technologies) by John Chambers and colleagues. R can be considered as a different implementation of S. There are some important differences, but much code written for S runs unaltered under R. R provides a wide variety of statistical (linear and nonlinear modelling, classical statistical tests, time-series analysis, classification, clustering, ...) and graphical techniques, and is highly extensible. The S language is often the vehicle of choice for research in statistical methodology, and R provides an Open Source route to participation in that activity. http://www.r-project.org/ http://cran.r-project.org/ rproject http://bits.ohloh.net/attachments/7154/Rlogo-5_med.png http://bits.ohloh.net/attachments/7154/Rlogo-5_small.png 64 4.31579 19 767531 767531 3926 2009-11-22T00:45:45Z 2009-11-22T00:38:33Z 1997-09-01T00:00:00Z 2009-11-01T00:00:00Z 17 567462 42 C gpl GNU General Public License 2.0
