Re: [Rd] Improved Nelder-Mead algorithm - a potential replacement for optim's Nelder-Mead

i have a question concerning the Nelder-Mead algorithm in R. As far as i can see, the shrink operation is not included in the optim() function. Does anyone know an implementation of the Nelder-Mead algorithm including this operation in R? Could maybe someone send me one? I would try to write the code on my own, but due to my doctor thesis i am a little under time pressure and would appreciate any help. Thank you in advance!
