Please try
 
	$ sudo apt-get install r-cran-rgtk2

which should also install a matching r-cran-cairodevice.

Gtk2 library mismatch. You didn't tell you which version of Ubuntu, R,
RGtk2, ... you are using so it's a bit hard to guess.

FWIW on my Ubuntu machine(s) at work, I install these from CRAN
sources and that works without a hitch.

Consider signing up on r-sig-debian where Debian / Ubuntu questions
are more topical.

Hth, Dirk
