[R] skeleton for C code?

Dear R experts---I would like to write a replacement for the read.csv function that is less general, but also more efficient.

could someone please provide me with a skeleton function that shows me how to read the arguments and return a data frame for a call to a C function that handles

     returned.data.frame = my.read.csv(file, header = TRUE, sep = ",", quote="\"", dec=".",

              fill = TRUE, comment.char="", ...)

this may be very difficult, of course, in which case writing such a function would not be worth it. I guess I would be happy just to learn how to return a basic data frame that holds data vectors that are either strings or numbers---nothing more complex.

help appreciated.
