R help - Jan 2002 - lattice dotplot and graphic devices on Windows

I am using R1.4.0 on WindowsNT (the precompiled version from Brian Ripley's
website) and the lattice package (version details are at the end of this
message).
After producing a lattice dotplot, I want to insert the graph into a
MicrosoftWord document. With "ordinary" R-graphics, I have done this
successfully by copying the graph as a metafile to the clipboard and pasting
this into my word document.

However, when trying to do the same with a lattice plot, I encountered some
problems:

# simple example:
> library(lattice)
> test <- data.frame(a =
c("A","A","B","B"), x = 1:4, g
rep(c("g1","g2"),2))
> trellis.device(width=3.35, height=3.35, color=F)
> dotplot(a~x, groups=g, data=test, panel="panel.superpose" )
# this is fine on screen, but when right-clicking on the picture and chosing
"Copy as metafile", an error is generated:
Error: A metafile can store only one figure.

# However, "Copy as bitmap" works (but quality is poorer when pasting
to
WinWord).
# What also works is chosing from the menu "File>Save As>Jpeg"
(or Bmp).

# As jpeg and bmp work, I try to print this to a file directly, but get an
error:
> dev.off()
> trellis.device("jpeg", quality=100, width=3.35, height=3.35,
color=F)
> dotplot(a~x, groups=g, data=test, panel="panel.superpose" )
Error in grid.newpage() : A jpeg file can store only one figure.
# same with bmp:
> trellis.device("bmp", width=3.35, height=3.35, color=F)
> dotplot(a~x, groups=g, data=test, panel="panel.superpose" )
Error in grid.newpage() : A bmp file can store only one
figure.

So my three points here are:
1) Is there a way to copy and/or save the graph as a metafile?
2) If not, can someone give advice which graphic format else is the best to
use here (it seems to me that bitmap is not)?
3) As saving (in jpeg, bmp) via the file menu works here, shoudn't these
graphic devices work with "trellis.device" as well?

Update your version of grid.  This is a known problem, reported here many
times and fixed in grid 0.5-1.

Heinrich Ritter commented that this had not been announced.  Since that
may be a common misunderstanding, let me explain.  It is not usual to
announce patch releases (here -1) of packages.  You would get tired of
hearing about them: there have been at least 70 since 1.4.0 was announced
on Dec 19.  (Your maintainers do get a bit tired of the flood sometimes
too.)  What we do expect is that you run update.packages() fairly
frequently, and certainly when you encounter a problem.

Since there were a few problems reported, here's a bit more information
about the bug-fix version of grid, 0.5-1.

The purpose of this version is to fix the following bugs:
 (i)   grid (lattice) output could not be saved in metafile format
 (ii)  non-grid output could not be saved in metafile format when
       grid (lattice) was loaded
 (iii) empty page at start of grid (lattice) postscript output
 (iv) empty page at start of non-grid postscript output when
       grid (lattice) was loaded
 (v)  copying grid (lattice) output from x11 to postscript (dev.copy)
       produced blank pages in postscript

The latest version of the lattice package (version 0.4-0) should work fine
with this new version of grid.
