[R] Can I ask for the C code inside an R function using .C?

[Francisco J. Zagmutt]

Well, if you have a slow modem connection and you are an average user that 
doesn't want (or doesn't know how) to compile the source code, you may spend 
half an hour or more downloading the windows binary. Then you realize you 
want to see a .C function and you will have to spend another 15 to 20 
minutes downloading the source tar.gz...OR you can lookup the specific 
function in the mentioned website in a fraction of the time.  Off course, 
overall if you check C or Fortran functions all the time you may want to 
have a local copy of the source.  I think is great that users have that 
flexibility, hence they should be aware of both options.

Cheers

,
you may prefer just to visit a web site and see the specific function that 
you want to learn about, rather than waiting another 15 to 20 minutes to 
download the source tar.gz.
