[R] ggplot2 - suggestion for facet_wrap/grid

Hi David,

I disagree ;)  Conceptually they are rather different: facet_wrap is
essentially a 1d layout, while facet_grid is a 2d layout.  This has
implications for how you specify the faceting, how the facets are
labelled, and how the scales can vary.  While I could probably force
both into a single function, this is rather against the philosophy of
ggplot2, which strives towards small objects which only do one thing.
This tends to make things a little more verbose, but I think it makes
things easier to understand.
