[R] Scripting capabilities for R

I'm in the final week of teaching a course to beginners using R and
S-Plus. Since I forbade the students from using the "point-and-click"
interface in S-Plus, they've become reasonably proficient at using the
command line in both programs.
Students really like the speed and ease-of-use of R for the vast majority
of their projects. I think they'd switch to R completely if they could get:
1) trellis graphics (I've encouraged them to try grid and lattice).
2) the full complement of multiple comparisons capabilities found in
3) the more comprehensive discriminant analysis routines in S-Plus 2000
and 6.0 - the ones with all the inferential testing as well as the
classification results (they use the MASS routines now. The S-Plus version
has more options to study the separations themselves).
4) Scripting capabilities.
Of these 4, their priority is for R to have S-Plus scripting capability. I
realize that they can get this using Emacs with ESS, but I found it
sufficiently daunting to teach rank beginners how to use R/S-Plus
proficiently in 10 weeks that teaching them how to use Emacs/ESS at the
same time scares the bejesus out of me.
I haven't seen any mention of this as a development priority. Is any of
this on anyone's "to do" list?
Thanks for such an incredibly robust program. Keep up the great work.
