Thank you Professor Ripley: >From your response it is clear that I left out something important, for which I apologize.
Part of the et cetera is another list. Your method, which would work otherwise, also converts the other list to its members. The program being called has an argument list like (a, b, c, d, e, w, x, y, z) where z is a list but the other elements are single variables (not lists or vectors). I have the values of (a, b, c, d, e) returned from the R function "optim" as results$par. I wish to call my function with those values, some others, and finally with that other list, z. Is there a way to do this without defining another variable "var" and listing its elements without the undesirable unlisting that terminal variable z? Thank you. Charles Annis, P.E.
