[ESS] Syntax highlighting in R - again!

[Paul Leo]

If you highlighing is working you can modify the colors via the emacs
editor using
Edit-> Test Properities -> Display Faces t
hen modify till you have what you like.

Hope that helps
Paul

Hi Peter,

It sounds like the default syntax highlighting is working for you.
ESS just doesn't highlight very much.  So if you've moved from an
editor like Tinn-R, you will probably be disappointed.  A while back,
I gave a hack that I have used to get more highlighting (for functions
in R's "base" package).  You can find my hack here:

http://www.nabble.com/Font-locking-td22839833.html

As other commenters noted, you might want to do the same thing with
other standard R packages (like "stats", "utils", etc.) to get
highlighting for all the the typical R functions.

Ultimately, I'd like to do what was recommended in that thread---write
some code to automate the whole process (i.e. automatically get the
function names from R packages and read them into the correct
variables in ESS), but I haven't had the time to learn the Lisp I
would need to do that.  Some day...

Hope that helps,
McKay
