[R] An small suggestion for the R team

[Tuszynski, Jaroslaw W.]

Jose,

While writing highlighters for jEdit, I assume you are familiar with
existing R and Rd highlighters for jEdit. R mode was written by Tobias Elze,
based on a file from Zed A. Shaw, and I wrote Rd highlighter. 

If you (or anybody else needs them) I can send a copy.

Indeed, the above are very good examples of how to contour the original
problem Gabor!
But the central problem is to make Good R highlighter, as I'm trying to do
for the programs Tinn-R and jEdit with this functions.

Is not possible differentiate the signal minus as a simple character
(word-word) from the mathematical operator minus (object-object).

I think that is more easy to remove all this functions/reserved words.

TIA,
