[R] rotated ylab with xyplot

[Austin, Matt]

Try

library(grid)
xyplot(y~x,data.frame(x=1:10,y=runif(10)), ylab=textGrob(label="my label",
rot=0))

Note in the ?xyplot the xlab/ylab section points to the 'main' parameter
where it defines that a list can be used, however string rotation parameters
are not in the list.  The helpfile notes that a grob object can be used.

The reference for lattice and grid is R Graphics by Paul Murrell.
