[R] Issue with match.call

Hi, I have a function that I'm writing. The arguments in the function are as follows RFF-function(qtype, qOpt,...){} i.e., I have two args that are compulsary and the rest are optional. Now when my user passes the function call, I need to see what optional args are defined and process

Hi, Something along these lines should get you there: RFF - function(qtype, qOpt, ...) { mc - match.call(expand.dots=TRUE) vec - c(flag,sep,dec) matchedargs - match(vec, names(mc), FALSE) } 'matchedargs' will be a vector of the positions in mc where it matched 'vec' (or 0 if it did not).
