TODO for this release
* Complete rdoc documentation
* Profiling and some optimisations
* Multicolumn legends (and specification)
ggplot 0.6
----------------------------------------
* it's now easy to change the default scales (and their arguments) with the set_default_scale function, see ?set_default_scale for more details (thanks to Bob Muenchen for the suggestion)
* new order aesthetic which controls the order in which elements are plotted
* min and max are now scaled the same way as y
* functions are silently dropped (e.g. aes(colour=col))
* coord_polar: add start and direction parameters, giving more control over the layout of the polar coords
* coord_polar: added my favourite pie chart example
* coord_trans now deals with groups appropriately, at the cost of decreased speed
* geom_abline, geom_vline, geom_hline: should now behave better in a wider variety of settings
* geom_crossbar: the middle line is now display thicker than the other lines, controlled by the parameter fatten (thanks to Heike Hofmann for the suggestion)
* geom_density: fix scale adjustment bug in geom_density
* geom_line, geom_text: all size measurements (now lines and text as well) are measured in mm, lines/paths default to paths 0.5mm wide
* geom_rug: new to add marginal rug plots
* geom_smooth: fixed bug where if se=FALSE x axis always includes 0
* qplot: allow qplot to use computed aesthetics too
* scale_discrete: all discrete scales now have labels argument which you can use to override the factor levels
* scale_size: legends resize to avoid overlaps
* scale_x_continuous, scale_y_continuous: new convenience functions xlim and ylim (and zlim) that make it even easier to adjust the limits of the x, y, and z axes
* stat_bin, geom_area: fixed bug in combination of stat_bin and geom_area that made it difficult to draw frequency polygons
* stat_bin: fixed bug which resulted in increased counts when the x axis was a categorical variable with a single level (thanks to Bob Muenchen for pointing this out!)
* stat_bin: no longer incorrectly warns that binwidth is unspecified when breaks are set
* stat_bin: now takes origin argument to manually specify origin of first bin (default is round_any(min(range), bin_width, floor))
* stat_boxplot, stat_contour, stat_density2d, stat_qq, stat_density: na.rm parameter added to the following statistics (thanks to Leena Choi for suggesting this)
* stat_function: new, makes it easy to superimpose a function on the plot
* stat_spoke: new, to make it possible to use geom_segment parameterised by angle and radius (thanks to Jiho for the suggestion)
* stat_summary: better documentation
* stat_summary: convenient auto wrapping of simple summary functions
Legends:
* preliminary legend merging code:
* consequence: legend type no longer specified in scale (e.g. size, identity, manual), but derived from geoms used
* better legends for smooth and pointrange
* fixed some examples where grob used instead of guide
Examples
* now easy to run all examples with all_examples_run(), or for an individual object with (e.g.) GeomPoint$examples_run()
