R help - Jul 2008 - R-source code of a function

Hi,
I know that if i want to see the SPLUS or R-source code of a function,i should
give the command
without the brackets.For example:
 rsquared.lmRobMM
function(x)
{
 str0 <- "Initial S-estimate"
 str1 <- "Final M-estimate"
 if(x$est == "final") {
  z <- x$r.squared
  attr(z, "info") <- str1
 }
 if(x$est == "initial") {
  z <- x$r.squared
  attr(z, "info") <- str0
 }
 oldClass(z) <- "lmRobMM.info"
 z
}
> 
Is there anybody knows how can i  access all linked code which maybe written in
the other languages such as c in above program?
Bests,
Arezoo

There is no linked C in the example above:  it would be called using 
.C() or a few other related functions.

But if you see one of those in some other function, you'll want to 
follow Uwe Ligge's advice in RNews on locating the source.  His article 
is online here: cran.r-project.org/doc/Rnews/Rnews_2006-4.pdf, on 
page 43-45.
