Most used R editors

- split the emacs editor as many part as you want.
- use a lot of keybindings.
...
I also tried Rkwards, Scilab (windows), JGR etc... but they are not

(for the biologist and bioinformatician, a R package which permitts to reproduce what pdb viewer does).
Does a Way exist to do something like that in R ?
Thanks,

web interface for R script??
Dear All,
I requiered your feedbacks about a web interface for R scripts.
I already tested RGG ( but it's not web).
and two of the CRAN list : Rserve & Rpad.
However, Rpad requieres some knowledge in Javascript, php etc...
and with Rserve I have to create a web interface entirely.
Rwui from the cran list seems attractive.
Did you ever test this one ?
Other suggestions are welcomed too
