Patch: fix segfault from empty raster
Hi,
A colleague recently came across an R crash, which I can boil down to
the following, running under Rgui on Windows 7:
library(ggplot2)
ggplot(data.frame(x=1, y=1, z=4.7), aes(x, y, z=z)) + stat_summary2d()
This reliably causes a segmentation fault. sessionInfo() below.
What's happening is that (for reasons which I'll discuss with the
ggplot2 developers) the 'colorbar' guide is being built with a zero-size
source raster.
In L_raster() (grid.c), this raster is not a "nativeRa...

...ensity. Histodot binning uses fixed-width bins just like
`stat_bin`, while dot-density binning uses variable-width bins. A new grob,
`grob_dotstack` is used to render the dots. (Thanks to Winston Chang)
* New fortify methods have been added for objects produced by the `multcomp`
package.
* `stat_summary2d` and `stat_summary_hex`. These are work like `stat_bin2d`
and stat_binhex but allow any summarisation function (instead of just
count). They are 2d analogs of `stat_summary`
* `facet_grid`: The space argument now supports `free_x` and `free_y` next to
`free` and `fixed, this allows the user...
