A sizeable R community has grown up around the [r] tag on SO. However, we are increasingly seeing a large number of non-programming related Qs being posted to the site. Also, some of the more open-ended or no-single-answer Qs that are highly thought of by the [r] users are being closed by SO Mods as they transgress the "What not to ask..." parts of the FAQ.
Whilst R is a programming language, it is far more than this, with people using high-level R functions and packages to do data analysis for both work and play. There is an active and vibrant R community that extended well beyond the concept of programming.
Some of us in the [r] SO community have been discussing the possibility of getting together a proposal for Area 51 for an R-specific Stack Exchange site. This site would embrace the entire R community and the myriad uses to which R is put. Statistical Qs would still be best housed on CrossValidated and R programming Qs could remain on SO, but everything else could be off-loaded onto the new site, as well as welcoming a wider selection of Qs. In some senses, it would be a little like the relationship between SO and Programmers; they coexist happily with different remits.
It has been noted that there are few, if any, language-specific sites proposed on Area 51. Is this because they would be inappropriate and have been deleted? Would such SE sites be welcomed if we could garner sufficient support from the R community at large? The proposed site would be very much in the spirit of environment-based sites such as Drupal, Wordpress, Ubuntu etc.
