I concur with joran. The output of a C function called from within R is a list of all its arguments, both "in" and "out", so each "column" of the dataframe could be represented in the C function call as an argument. Once the result of the C function call is in R, all that remains to be done is to extract those list elements using list indexing and give them the appropriate names.
