R-ians:
After some effort I coerced my code to do what I want but my syntax is a
kludge. Suggestions on more elegant syntax?
par <- NIM.results$par
do.call("Draw.NIM.POD.curve", list(par[1], par[2], par[3], par[4],
par[5], a.hat.decision, .... et cetera ...
It seems that I should be able to avoid defining the variable "par"
and then
specifying each of its elements, but all my attempts resulted in a list
whose first element is a list, rather than the elements of the list. And my
attempts at unlist were unsuccessful.
Thank you.

Try c(as.list(par), a.hat.decision, .... et cetera ...) We are guessing what any of these are, of course.

Would something like this work?
my.list <- as.list(c(NIM.results$par, a.hat.decision, etc))
do.call("Draw.NIM.POD.curve", my.list)

Thank you Professor Ripley:>From your response it is clear that I left out something important, forwhich 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.

Right you are! Thank you for finding my mistake. I have been trying all sorts of combinations and I just dropped the ball. Thank you and thanks to Professor Ripley! Charles Annis, P.E.
