A function in R can't exist unless its syntactically correct. Or is your function reading a text representation of an R function (from a file or user input as a string)? In which case it would be easier to check the syntax from R just by using 'eval' in a 'try' clause, and then pass the function object to C++ in the usual documented way (as an SEXP).
