[R] optim hangs without warnings or error

[Katja Hebestreit]

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
