optim hangs without warnings or error
Katja, this seems to be a bug. I can reproduce this under 64-bit R-2.15.3 / R-prerelease for Windows. It works with the results given by Ben Bolker under 32-bit R for Windows. Will inspect shortly. Best, Uwe

Hello, optim hangs for some reason when called within the betareg function (from the betareg package). In this special case, the arguments which are passed to optim cause never ending calculations. I uploaded the arguments passed to optim on: https://www.dropbox.com/s/ud507gbpt3gkbcp/optim_arguments.RData I appreciate any help. Cheers, Katja
