Hi Ravi, that's an interesting claim and N-M. Can you provide any reading matter to support it?

More importantly, the default choice of optimizer in optim should be changed from "Nelder-Mead" to "BFGS." Nelder-Mead is a bad choice for the most commonly encountered optimization problems in statistics. I really do not see a good reason for not changing the default in optim.
