Dear R list,

I have a package downloaded and looked up a function in there. Now I find
that it uses C code (.C call) to do part of its job.

However, when I wanted to look that part up by using getAnywhere()  I was
told that no object of that name could be found. Then I tried typing C.("
funct.name") which only caused R to crash.

Is there any way to look up the function?

I'm not an expert and don't understand much of the technicalities mentioned
in the  Writing-R-extensions manual. I only would like to see how the
method I think is used is actually implemented.

I use R.2.13.1, Windows 7. The package I'm referring to is adehabitatLT,
function acfang.ltraj -> res <- .C("acfangl",...)

Many thanks in advance!

Jacqueline
