[R] Print grid/ggplot to a metafile

[Dieter Menne]

Dear UseRs called Hadley, or Paul,

I am trying to print an edited ggplot2/grid graphics to a metafile. With the
commented line below it works, but when I edit the plot by uncommenting the
line, it fails, because it's illegal to have 2 graphics in a metafile. It
works with pdf, but even then I get two plots, which is a nuisance.

I found a workaround by using windows(); savePlot, but it only works in
interactive mode, not when called with something like (Windows)

rterm --no-save < printit.r

Any ideas?

Dieter
