          RSiteSearch("solving nonlinear equations") just returned 42 hits for me, many of them potentially relevant to your question. And there are more capabilities than what I found listed in the first few responses, including nlme in addition to optim, nls, etc. A more focused question as suggested in the posting guide! might elicit more informative responses.
