search for: createlockfile

Hi there, I was doing great with R, ggplot and tikzDevice, when suddenly it stopped working. I can do a plot just fine on the R online graphics device. I can also open a tikzdevice via tikz(). However, the plot (both ggplot and R graphics plot) call leads to the error: "createLockFile(lockname): cannot create lock file" I see that this is related to my OS, namely Ubuntu 10.04. I already checked if I have write access to /var/lock via touch /var/lock/test && rm -f /var/lock/test which gave no errors... Now my actual question: How can I inspect which file R wants...
