ggplot changes

Past changes to ggplot

Many, many tweaks and bug fixes.
Most grobs now take a weight argument which is passed on to the appropriate statistical transformation.

Fixed some bugs in chop, qplot, ggbar, ggboxplot and gg2density.
Added ggvline and gghline for drawing vertical and horizontal lines, respectively.
ggboxplot will now draw boxplots in either direction
Removed annoying black border from saved output
Added ggerrorbar to add error bars to a plot (reference implementation provided by Timm Danker, thanks Timm!)
Fixed a few bugs which prevented you from using character shapes
Fixed a bug with setting the range of a transformed axis
Tweaked colour scales again

An easy way to save ggplots with sensible defaults: ?ggsave.
Control the aspect ratio of your plots using ggopt("aspect.ratio" = 1)
More plot templates: ?ggmissing, ?ggstructure ?ggorder. Plot templates are a good place to look for example code for making more complicated plots.
Many data related functions moved in to the reshape package.

A new function, qplot, to quickly produce basic ggplot graphics using a similar interface to plot.
A fluctuation plot template, see ?ggfluctuation.
Some new grob functions: 1D density (ggdensity), ribbons(ggribbon), stacked and dodged bar charts (ggbar).
An easy way to set specific aesthetic attributes for an entire grob (eg. blue points, or thicker lines). Just specify the value you want outside of the aesthetics list, eg. ggpoints(p, colour="blue", size=4).
Can now setting many previously fixed defaults: background colour, axis label and title text, position of legend, colour of strip label text and background, ... See ?ggopt for more details.
Functions to make reordering and combining factors easier, see ?reorder_factor and ?combine_factor.
Some (hopefully) improved defaults for colour scale and scale breaks.
A full set of scales for mapping the fill colour.
Legend labels so you can see what variables the legends correspond to.
