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.

To install or update, run:
install.packages(c("ggplot2", "plyr"))

ggplot2 0.8.8 (2010-07-02) ----------------------------------------

This version fixes the following 23 bugs:

* coord_equal finally works as expected (thanks to continued prompting
from Jean-Olivier Irisson)
* coord_equal renamed to coord_fixed to better represent capabilities
* coord_polar and coord_polar: new munching system that uses distances
(as defined by the coordinate system) to figure out how many pieces
each segment should be broken in to (thanks to prompting from
Jean-Olivier Irisson)
* fix ordering bug in facet_wrap (thanks to bug report by Frank Davenport)
* geom_errorh correctly responds to height parameter outside of aes
* geom_hline and geom_vline will not impact legend when used for fixed
* geom_hline/geom_vline: intercept values not set quite correctly
which caused a problem in conjunction with transformed scales
(reported by Seth Finnegan)
* geom_line: can now stack lines again with position = "stack" (fixes #74)
* geom_segment: arrows now preserved in non-Cartesian coordinate
system (fixes #117)
* geom_smooth now deals with missing values in the same way as
geom_line (thanks to patch from Karsten Loesing)
* guides: check all axis labels for expressions (reported by Benji Oswald)
* guides: extra 0.5 line margin around legend (fixes #71)
* guides: non-left legend positions now work once more (thanks to
patch from Karsten Loesing)
* label_bquote works with more expressions (factors now cast to
characters, thanks to Baptiste Auguie for bug report)
* scale_color: add missing US spellings
* stat: panels with no non-missing values trigged errors with some
statistics. (reported by Giovanni Dall'Olio)
* stat: statistics now also respect layer parameter inherit.aes
(thanks to bug report by Lorenzo Isella and investigation by Brian
* stat_bin no longer drops 0-count bins by default
* stat_bin: fix small bug when dealing with single bin with NA
position (reported by John Rauser)
* stat_binhex: uses range of data from scales when computing binwidth
so hexes are the same size in all facets (thanks to Nicholas Lewin-Koh
for the bug report)
* stat_qq has new dparam parameter for specifying distribution
parameters (thanks to Yunfeng Zhang for the bug report)
* stat_smooth now uses built-in confidence interval (with small sample
correction) for linear models (thanks to suggestion by Ian Fellows)
* stat_spoke: correctly calculate stat_spoke (cos and sin were
flipped, thanks to Jean-Olivier Irisson for bug report and fix)
