Subject: R crash using Sys.which on Windows
In-Reply-To: <2090370034.43069.1399400934031.JavaMail.zimbra@openanalytics.eu>
This is a change in behaviour of the Windows API function since the code
was written (years ago). It will be changed in R 3.1.1: meanwhile you
can always use the shortPathName to abbreviate the name.
