Hi Ramon:

That's a very interesting suggestion.  To take this further, somebody 
needs to volunteer to write an R scanner.  Details on what's necessary 
are available @
http://www.gnu.org/software/idutils/manual/html_node/Defining-scanners.html#Defining-scanners

And, for those of you involved in large statistical software projects, 
this package deserves a look.  Currently supported languages are 
C/C++/Java, Assembly, Perl and Lisp (hint, hint, ESS brethren). 
Personally, I'd also like to see a SAS scanner.  When I get some free 
time (ha, ha), I'll have to take a closer look at this.

Thanks,

Rodney
