Forgive that last mail, I have now realised it was all complete b*ll*cks ;-)
-----Original Message----- From: michael watson (IAH-C) Sent: 07 July 2003 15:12 To: '[EMAIL PROTECTED]' Subject: Xvfb and R Hi I have recently installed and implemented Xvfb (X virtual frame buffer) so that I can create jpegs using R over CGI (SUSE Linux 8.1 and Apache 1.3). I have noticed that in order to do this, a file (Rplots.ps) is created in my cgi-bin directory everytime a cgi script is run. This could cause problems though as I have a multi-user system where it is possible that two different users will run cgi scripts at the same time, and both will be writing/reading Rplots.ps at the same time - a conflict! I am simply using the jpeg() function of R. On a different server, where I'm not using Xvfb but the real X server, I do not get this fule Rplots.ps so I am guessing that there is some magic going on behind the scenes, though I may be wrong. Can anyone explain what is happening, and if I can make R/Xvfb create a DIFFERENT file, say in /tmp/, with a unique name, everytime a cgi script is run?
