[R-pkgs] ggplot2: version 0.8.4

[Hadley Wickham]

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 0.8.4 (2009-12-08) ----------------------------------------

* aes and aes_string both convert prefixes to full names
* aesthetics: corrected list of aesthetics to include american spelling of
  colour as well as base R abbreviations
* aesthetics: fix bug in detecting which aesthetics are calculated
* aes_string treats NULL as "NULL"
* annotate now works with missing x and y (e.g. for geom_rect)
* continuous scale limits now automatically sorted
* coord_polar: fix bug if breaks not all inside limits
* facet_wrap: can now specify both ncol and nrow without getting an error
* facet_wrap: now works with statistics that produce both x and y values (e.g.
  stat_qq)
* fullseq now adds additional break on bottom if necessary, so that the
  include.lowest argument in cut never comes into play (this the source of a
  potential bug in histograms)
* geom_boxplot: alpha now affects fill colour of boxes only
* geom_path correctly switches to segments if varying alpha used (thanks to
  Karl Ove Hufthammer for the report and Baptiste Auguie for the fix)
* geom_point: the alpha aesthetic now also affects the fill.
* geom_ribbon always sorts input to avoid problems with certain pathological
  inputs
* geom_smooth was incorrectly applying alpha to line colour in the legend
* nullGrob renamed to zeroGrob to avoid name conflict with grid
* position_collide now works with missing values
* position_stack: fixed bug in detection of overlap for negative values
* scale_discrete_position now uses drop argument to force dropping of unused
  levels
* scale_gradient, scale_gradient2 and scale_gradientn now uses label
  parameters, if supplied
* scale_x_inverse, scale_y_inverse now actually work, and added recip as alias
* stat_qq now correctly groups results
* stat_smooth will not try and fit a line to 2 or fewer points (previously
  didn't try for only 1 point)
* stat_spoke now works with reversed scales
* grouping: now consistent between different geoms (Issue #33)
