What are R and CRAN?

R is `GNU S', a freely available language and environment for statistical computing and graphics which provides a wide variety of statistical and graphical techniques: linear and nonlinear modelling, statistical tests, time series analysis, classification, clustering, etc. Please consult the R project homepage for further information.

CRAN is a network of ftp and web servers around the world that store identical, up-to-date, versions of code and documentation for R. Please use the CRAN mirror nearest to you to minimize network load.

Submitting to CRAN

To "submit" to CRAN, simply upload to and send email to Please indicate the copyright situation (GPL, ...) in your submission. Note that we generally do not accept submissions of precompiled binaries due to security reasons (we have no means to check for viruses etc. for the big variety of platforms that R runs on). All binary distribution listed above are compiled by selected maintainers, who are in charge for all binaries of their platform, respectively.
