[R] Ggplot2: saving a grid with multiple plots

Dear all,

Thanks for all your responses. It looks like I was misinterpreting the
capabilities of ggsave(). That can only handle the "basic" ggplot2 plots
(which can be very elaborate). This behaviour is decribed at the end of
chapter 8 in the ggplot2 book, but I missed that.

Opening and closing a device works well.

than asking him to perform a post-mortem examination: he may be able to
say what the experiment died of.

No idea what the easiest way would be if you want both window and 


pPoint <- qplot(unemploy/pop, psavert, data=economics)
pPath <- qplot(unemploy/pop, psavert, data=economics, geom="path")

pushViewport(viewport(layout = grid.layout(2, 1)))
print(pPoint, vp = viewport(layout.pos.row = 1, layout.pos.col = 1))
print(pPath, vp = viewport(layout.pos.row = 2, layout.pos.col = 1))
