Problems with betareg()

Hi,

In using the betareg package, I encounter the following error message:

Error in lm.wfit(x, linkfun(y), weights, offset = offset) :
 NA/NaN/Inf in foreign function call (arg 4)

Any help will be most appreciated. Thanks in advance.

We can't possibly help you with this amount of information. Please provide 
a small reproducible example, preferably with a (small) artificial data 
set or with one available in R. (Also see the posting guide, linked at the 
end of this e-mail.)
