I can't parse your metacode, so I really don't understand your
question. Have you worked the examples in the "?integrate" help page?
Also, do you understand the "..." argument to the "integrate" (and
other) functions"? If the answer to the latter is "no", I suggest you
also read Venables and Ripley, Modern Applied Statistics with S.
If that is not adequate and you'd like more help from this listserve,
please submit a simple, self-contained example that seems to come the
closest to something you want but can't quite get, as suggested in the
posting guide! "www.R-project.org/posting-guide.html".
I know this didn't answer your question, but I hope it helps you.
Best Wishes,
Spencer Graves
