[R] print.trellis draw.in - plaintext (gmail mishap)

[Felix Andrews]

The problem is that you have not pushed your viewport so it doesn't
exist in the plot. (You only pushed the layout viewport).

> grid.ls(viewports = TRUE)
ROOT
  GRID.VP.82

Try this:

vp <- vplayout(2,2)
pushViewport(vp)
upViewport()
grid.ls(viewports = TRUE)
#ROOT
#  GRID.VP.82
#    GRID.VP.86
print(p, newpage = FALSE, draw.in = vp$name)
