In the Sage command line, you can type sage: r? to get some very basic info, and sage: r.[tab] to get various commands. This part of the interface still needs some work, though it suffices (particularly via r.eval()) for many needs. You do NOT need to reinstall R; a full copy of R (with all recommended packages) is in any recent Sage. However, based on your earlier emails in the thread, you may want to start Sage, and then type sage: notebook() to launch the web server on your own computer, from which you can get a Mma-style worksheet and do all R computations in there, by simply selecting 'r' from the drop-down menu at the top which would currently read 'sage', or by typing %r at the beginning of each cell you want to use R in. You are, however, right that there is very little easy-to-find documentation on how to use R within Sage, and we VERY much welcome improvements on this front. The worksheets http://prep.sagenb.org/home/pub/34/ and http://sagenb.org/home/pub/2232/ might have a few tidbits for you, and the thread at http://groups.google.com/group/sage-support/browse_thread/thread/b8411dfebdb54406/0bca74c09bd4145a?lnk=gst&q=r+integration#0bca74c09bd4145a may as well. In particular, if anyone wants to help improve this (though again, quite a bit already works seamlessly), you may be interested in the following talk (mine) at useR! 2010 next week: http://user2010.org/abstracts/Crisman.pdf We definitely need experts, and also really crave feedback on how Sage can best be of use to the R community (why R is useful to Sage should be obvious).
