This is a related remark to this topic and the icon topic of last week.
I'm not sure how file associations work between OS X apps and their 
extensions, however R.app doesn't appear to "own" any file extensions 
when it is installed, and they have generic or blank icons. Perhaps the 
individual keen on making icons from the email discussion last week 
could make new icons for "*.R" files, which might look like R-code with 
the R logo; an icon for "*.RData" which could look like those DB 
cylinders with the R logo; and another icon for "*.Rd" files 
(document-like text with the R logo?).
I forget if I had to manually get the "*.RData" extension to "Open 
with..." R.app, but this should be an automatic association after 
install; same goes for the "*.R" files.
The default behavior for double-clicking an "*.R" file should not open 
XCode, and should not be associated with an XCode "*.r" Resource Manager 
file icon. (I'm defiantly not sure if app file ownership in OS X is case 
sensitive, because in an ideal UNIX world "*.r" extensions and "*.R" are 
different, which they are in this case.)
Anyways, just a thought.
