[R] nls NAs

I got some help on this. While it did not fix the problem with nls, one can
get around the problem by creating a data frame with the NAs excluded. As
warm.10<-nls(umoles60~alpha*exp(beta*T10cm),start = start,data=warming2)
Note there is also a package on on CRAN(nlmrt) that tries to be more
aggressive in finding a
solution to nls type problems. The function wrapnls() in nlmrt runs a
Marquardt code then
nls (same calling sequence, but will not yet handle weights, nor every
expression, though it does most).
