Hello, Quick question. I have written a C function - I would like to make it return two vectors to the R environment - one STRSXP vector, and one INTSXP vector. Is this possible/ easy to do using the API? I looked, but could not find the answer to this question in the "Writing R Extensions" guide.
Put them in a list? The SEXP function in the .Call() interface then returns a list wich you unpack on the R side. There are plenty of examples in the base code and in numerous contributed packages.
Thanks very much for your help! Charles [[alternative HTML version deleted]]
