Documentation for ggplot2 and main website here .
Also you can checkout the crantastic page  for ggplot2.  This page includes reviews, ratings, related packages, and some additional links.

Here is the R script  for this session.  I sent the other datafile via email.

Outline

Work with a real example
    Much like SAS, half the battle can be getting the data in and in the right format
    Pick out some data you actually have and might want graphs of
ggplot2: pretty graphics fast
    Fast graphics, but also an entire environment or grammar for them
    Handout (Geometric object = geom; graphic object = grob)
    qqplot() , the simple way
    ggplot() : the idea of elements and layering
fortunes: better than a coffee break
    Usually true, and usually from good names

Learning Objectives

Start thinking in terms of the grammar of graphics (ggplot2)
Choose data to work with over the next few weeks
