[R] Profile on optim/nlm

[Steve Roberts]

Greetings,

Before I reinvent the wheel has anyone done a profile function for a 
fit using optim (or nlm)?  (like the buggy profile.ms in S+) . It 
seems a bit tricky as the function to be minimised has to have 
arguments corresponding to the variables being fitted - which is one 
less than the function provided to optim()... I guess you can create 
another function on the fly somehow.

Cheers,

Steve.
