[Rd] How can I call a function R from C

[Ricardo Rios]

Hi wizards, I have a function in R for example:
anyfunction<-function(beta0, popsize, maxgen),

but I have a  function in C  for example:

SEXP otherfunction(SEXP beta0, SEXP popsize, SEXP maxgen)

I call it function with .Call but I need to call to anyfunction on
otherfunction. Does somebody know how to do it?
