[R-sig-Geo] Saving plot as PDF from functions levelplot and gplot from rasterVis package

[Edzer Pebesma]

No:

require(lattice)
pdf("x.pdf")
xyplot(1~1)
dev.off()

produces the pdf with the plot I expected.

Calling print() on trellis objects is needed when this is not the
default action, for instance in a loop or a { } block where the plot is
not the return value. I guess that this is the same for gplot.
