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))
