Hi,
As Uwe said, this is not really the place to get support for Ubuntu.
They have excellent forums. But the problem seems to be that GRUB was
not correctly installed. Run an ubuntu live cd and reinstall GRUB from

Hey everybody,
I am trying to generate multiple boxplots on one page by using the layout ()
function. This works really well but the plots are always badly proportioned
(3 times wider than high) and much too small to be easily readable. I have
tried reducing margins to allow for bigger plots,
It woks fine.
Thanks very much.

I certainly don't have anything against the WIKI, but I think that the
