[This is of potential interest primarily to bash users and R package developers (hence the posting to r-devel only). Others, feel free to ignore.] I have been using bash's command completion features [1] for a while now, to the point where I expect everything to just work when I hit TAB. Since there was no bash completion for R (that I knew of), I took a stab at it myself last summer. This was my first major effort in bash programming, so it's far from perfect, but it mostly works. In case anyone's interested, the script is available at http://www.stat.wisc.edu/~deepayan/R/R.bash_completion which has more details on installation and use. Any feedback/improvements appreciated. -Deepayan [1] http://www.caliban.org/bash/#completion
