Full_Name: Chris Paulse Version: 2.1.1 OS: WinXP Submission from: (NULL) (129.98.60.134) This seems strange. I have a small block of code that repeatedly calls rbinom. I put a break in there in case it returns NaN, as I've been having problems with this. Here is a transcript from the debug session: Browse[1]> theP [1] 1 Browse[1]> yleft[dataIndex] [1] 3 Browse[1]> rbinom(1,3,1) [1] 3 Browse[1]> rbinom(1,yleft[dataIndex], theP) [1] NaN Strange, huh?
Please supply a reproducible example as both the FAQ and the posting guide do ask.
