ggplot2
===================================

ggplot2 is a plotting system for R, based on the grammar of graphics,
which tries to take the good parts of base and lattice graphics and
avoid bad parts. It takes care of many of the fiddly details
that make plotting a hassle (like drawing legends) as well as
providing a powerful model of graphics that makes it easy to produce
complex multi-layered graphics.

examples of ggplot in use.

Changes in version 0.5.4 ------------------------------

* border now drawn on top of geoms, instead of below - this results in
better appearance when adjusting scale limits
* ggplot() + aes() now modifies existing default aesthetic mapping,
rather than overwriting
* polished examples in facet_grid

Changes in version 0.5.3 ------------------------------

* added experimental scatterplot matrix, see ?plotmatrix
* added new border.colour and grid.minor.colour options for better
control over plot appearance
* updated theme_bw to do better when drawing a plot with white background
* better default colour choices for gradients (and more discussion in examples)
* fixed bug in ScaleGradient2 where scales with different positive and
negative ranges were not scaled correctly
* allow expressions as result from strip.text
* fixed rare bug in geom_vline and geom_hline
* fixed example in geom_abline
* tweaked display of multiline axis labels
