[R-SIG-Mac] Bug running pbinom() in R-GUI?

[Rob J Goedman]

Hi George,

This was indeed pointed out a couple of weeks ago. At that time it 
showed up for
nbinom for low probabilities.

It only occurs using the R GUI, not using a terminal.

Its on my list to try and understand why this happens. Thanks for 
reporting it.

Regards,
Rob
