probably this has used up sufficient disk space in the mail archive already, but anyway a bit of support to the initial request: one of the very first things I did, when I started using R, was adding

cd <- setwd
pwd <- getwd

to my .Rprofile. and when I encouraged colleagues to try R out, the 'top three' questions where

"how can I get out? I tried ^C, exit(), quit(), but nothing works"
"how can I change the directory? `cd' does'nt work"
"where am I? `pwd' does'nt work" (`pwd' is something like a 'local
speciality', I presume...)

this is of course a marginal obstacle for new users, but avoidable all the same. (and maybe most people (like myself) in the first place don't think it important enough to post it -- maybe it _would_ be in the FAQ otherwise...)

so, _if_ 'cd' would be recognized in future releases, it would'nt do any harm, would it?
