[Rd] copy metafile from window() device fails when lattice/grid is (PR#1242)

[andy_liaw@merck.com]

Dear all,

I'm running into a rather strange problem that hasn't happened before
R-1.4.0.  If I make a plot on a window() device, and use the menu to either
save to a metafile or copy to clipboard as a metafile, I get an error
message in the R console:

Error: A metafile can store only one figure.

This only happens when the lattice (and grid) package is attached,
regardless of whether the plot is Trellis or non-Trellis.  If I detach both
lattice and grid, and make the plot on a fresh window() device, I have no
problem getting the metafile.  If I try trellis.device(win.metafile,
"try.emf", bg="white"), I get 

Error in if (color) { : argument is not interpretable as logical

but the device is openned.  If I try to make a trellis plot, I get

Error in grid.newpage() : A metafile can store only one figure.

Any idea how to get around this problem?  TIA!!

Cheers,
Andy
