Roger,
Check capabilities() to be sure that 'cairo' shows as TRUE.
If it shows FALSE, be sure to install the cairo and cairo-devel RPMs and
re-build R so that cairo support is available. You may just need the
'cairo-devel' RPM if the 'cairo' RPM is already present.
Also, as an aside, F7 went EOL on June 13.
If that is not helpful, post back.
Regards,
Marc
