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 accordingly...what I have so far is.. RFF<-function(qtype, qOpt,...){ mc <- match.call(expand.dots=TRUE) } I need to see what all args have been sent out of vec<-c("flag","sep","dec") and define if-else conditions based on whether they have been defined. How do I do this?
