Be aware that the effects of calls to par usually only last for the
duration of the graphics device, not the R session. If you put a call
to par in your startup script, then it will open a graphics device and
set the option, but if you close that graphics device and do another
plot then a new graphics device will be started with the default
parameters rather than what you set in the startup script.
You can set some of the options (including background color) when
starting a graphics device, that may be the better option.
There was some discussion a while back on having global options for some
of the graphics defaults, but I don't think anything has been
Hope this helps,
