[R] C code and R

[Agustin Lobo]

A couple of questions on calling C programs
from R functions:

1. Is there any other guide on this matter in addition to
Writing R Extensions ?

2. Writing R Extensions starts dealing with C programs
assuming that those have already been compiled:
"Interface functions .C and .Fortran

These two functions provide a standard interface to compiled code that has
been linked into R,... "

Are there any constraints that should be considered 
at compiling a function that is intended to be called by R?

Splus (unix v 3.x) used to have an script 
(Splus COMPILE) to make sure that the compilation was done
with the proper flags. Is there an equivalent R COMPILE 
script?

Thanks

Agus
