Off list I sent the OP a note that wrapnls() from nlmrt calls nls after
nlxb finishes. This is not, of course, super-efficient, but returns the
nls-structured answer.

Dear Prof. Nash,
I tried to run nls with the nlxb function and as you mention it is fairly
slower in terms of running the code. However, if I would have used this
function earlier I would have saved a lot of time trying to find the start
values. The output looks a little bit sloppy but I think it is very usefull
to use in combination with nls.
Thanks
Robbie
