[R] Create graphs from text console

Also check out the GDD package created by Simon Urbanek if bitmap does
not fit your needs. On some systems, bitmap is slow or produces an
inferior quality plot, in part because anti-aliasing is not supported
(at least on my system). GDD, however, produces excellent anti-aliased
graphs using the GD Graphics Library with Freetype support instead of
ghostscript. That said, GDD is still in beta and has a couple of missing
features, such as lack of support for different line widths in graphs
(as of 0.1-7).

Via bitmap() (i.e. postscript with ghostscript postprocessing).
