[R] problem with win.metafile( ): traceback()

[Paul, David A]

In R1.8.0 for Windows, immediately after I 
execute win.metafile(...) and lset(...) I get the 
following values for .Device and .Devices:


> .Device
[1] "win.metafile://.../plot1.wmf"

> .Devices
[[1]]
[1] "null device"

[[2]]
[1] "win.metafile://.../plot1.wmf"


However, when I change to

> trellis.device(win.metafile, 
+   file = "//.../plot1.wmf", 
+   width = 8.5, height = 6.25)
>
> lset( list( background = list(col = "white")))

I get _no_ errors, and xyplot(...) creates the
appropriate windows metafile.

Could you check what the value of the .Device variable (and .Devices as
well) 
is at this point ? And not that it should matter, but what happens if you
use

trellis.device(win.metafile, file = "//.../plot1.wmf",
               width = 8.5, height = 6.25)
