Hi Thomas, Thanks for the note. I'm not sure about a lot of things. Setting the formal defaults then calling the function seem straight forward. I just assumed it would be like setting list values, or the C equivalent of calling formals(fn)<-list(a=1, b=3).
Following your suggestion, I can get the names of the parameters used in this user defined function, but am not sure how to do what you are suggesting. For instance, how do I call the function after I use setVar. Could you point me to an example? Thanks again!
