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 to create? It
fails both when called from inside emacs via ESS mode and when called from
the command line. I am out of ideas...

Any advice on how to inspect what is going on here?

Thanks in advance
