I get this error message when I call bugs() from R2WinBUGS.
"Error in while (.regexpr("\r", info) > 0) { : argument is of length zero"
A simple example is shown below. The curious thing is that I get no error when I run it with R on Debian Linux (lenny with Wine). I searched the BUGS archives but found no postings of this error.
It happened after I installed on a new PC (running Windows XP) R-2.10.1, R2WinBUGS, and WinBUGS14 (patched and keys updated).
Any thoughts on why and how to fix it?
