There are several problems, here. The first is that RKWard up to version 0.5.4 will crash when used with rJava. This is fixed in the current development version, but not in an official release, so far. If you are using Ubuntu, you may be interested in trying our daily builds (https://launchpad.net/~rkward- devel/+archive/rkward-dailys). Otherwise you can compile the development version yourself, following these instructions: http://p.sf.net/rkward/svn . However, the error message you posted indicates that there is another problem. This is unlikely to be related to gnome/KDE. Rather, I would guess that you have several versions of R installed, and the one used by RKWard is not properly configured for use with java. Try R CMD javareconf . Re-installing library rJava from within RKWard might also help (run install.packages ("rJava") in the RKWard R Console window. Regards Thomas
