[R] Export nls object to text file

[R. Michael Weylandt]

You can save it as an R Data file using save() and then reload it with
load() -- there's not a natural way to make it something that lives
nicely in a text file (since an nls object is quite complex) -- if you
are just going to be using the object again in R I'd recommend the
first. If you need it in some other program can you at least identify
which attributes you need? sink() will also be of help (in conjunction
with various print methods)
