I'd strongly recommend not touching (or adding to) those. Note the
"Private" there. :) Those are the languages built into Xcode. Apple
does provide a way to add your own without modifying the system. I'm
not 100% sure the path I gave is right as I've seen different ones, e.g.
http://kbase.wincent.com/old/knowledge-base/Xcode_Text_Macros.html

Ah, I just moved the files to this path and they registered with Xcode
- it seems to have changed between 2.x and 3.x:
~/Library/Application Support/Developer/Shared/Xcode/Specifications
That one is correct. Put the files in there, and in an Xcode project,
open an R file, do a "get info", and change the "File Type" to
sourcecode.R.
When I drag those two files to that directory, Xcode does some
highlighting but only of non-reserved words and comments, and also
does "(" and "{" matching if you move the cursor forward over a ")"
or "}", but not if the cursor is moved backwards.) Also shows some
code completion. I'm not sure what was _supposed_ to happen, but I
do see some behavior that suggests _some_ of those efforts were
having a desired effect.
So, it wasn't working in that path I gave first. What you were
probably seeing was Xcode interpreting the file as a rez (resource)
file, not R. But try the path above. Since they share the same
extension, you'll have to select it manually (as above).
Finally, I don't know the details of the internals of those files. I
made a quick five minute hack at it, adding the keyword list, calling
it "R", but not much more. It's *definitely* buggy and will need work,
but should give someone a push in the right direction. Google will help.
Cheers,
