<no subject> -> parameterizing a call to nls()

<...>

I would like the nls function to scroll through a list of different types of
optiontypes, c(?c?,?c?,?p?,...) for example.

I have little understanding how nls treats IF commands in general and how it
treats a list of non-numerical flags. Any help on this would great.
Apologies again for what I am sure is a simple question.

Glenn,

Welcome to R, and welcome to the R finance community.

Someone here may be able to answer your question (I can't), but you may find 
more people with deep experience in the nuances of the nls function on the main 
r-help list.  Your query was well-formed, so while I usually recommend against 
cross-posting, in this case I think you might get a more complete and timely 
answer if you repost to r-help (with a subject line, of course, perhaps 
"parameterizing a call to nls()")

Regards,
