request for ggplot2 to make facet_wrap order vertical (currently does horizontal)

[WaterLynn]

We spoke briefly at JSM on this.

as.table=TRUE #starts image in top right (default)
as.table=FALSE #starts panel in bottom right

both still order horizontally.

would be nice to start top right and then go down that column before moving to the column to the right, this is useful in things like cohort analysis where you are tracking populations based on length over time (so you want years to be on top of one another).

example of as.table usage here
