R help - Jul 2006 - Problems with character spacing in windows metafiles...

This problem was posted a couple years ago here:

http://tolstoy.newcastle.edu.au/R/help/04/01/0231.html

Using Windows XP with R 2.3.1, I am now experiencing the same problem again:
when a plot is saved and/or copied as a WMF, the labels do not have the
correct character spacing.  I am trying to insert the WMF into a MS Word
2003 document (my first mistake, I know), but even when the WMF is opened
with other graphics software, the problem remains.  Must be something with
the way the WMF is written.

The strange this is that I was able to do this on another computer with a
slilghtly older version of R (2.2.x?), and did not have the problem.  The
version of Microsoft Word was the same on both, and the code did not matter
(any basic plot with any font had its text labels squeezed).

I've done some searching and haven't come up with any good solutions. 
For
Windows users, the WMF is the most convenient format for saving vector
graphics.  EPS is not an option for me.

Any help would be greatly appreciated.

Cheers,
Dan

I am using the multcomp package for doing multiple comparisons. Since the data I
am handling is huge the number of comparisons are also large. I am interested
in:
1>  Breaking down my plots to get rid of the clutter that happens when
plotting the entire data set. How do I pass only part of the data to the plot
function ?
 
fungus.cirec<-simint(Fungus.yield~Habitat, data=fungus,conf.level=0.95,type
=c("Tukey"))
plot(fungus.cirec)  #This plots the entire data. I want to plot part of the data
only
 
2>I am also interested in getting rid of the field name associated with each
categorical variable.
Here is what the part of the data looks like
 
Habitat Fungus.yield
Birch 20.83829053
Birch 22.9718181
Birch 22.28216829
Birch 24.23136797
Birch 22.32147961
Birch 20.30783598
Oak 27.24047258
Oak 29.7730014
Oak 30.12608508
Oak 25.76088669
Oak 30.14750974
Hornbeam 17.05307949
Hornbeam 15.32805111
Hornbeam 18.26920177
Hornbeam 21.30987049
Hornbeam 21.7173223
When it plots labels it as HabitatBirch-HabitatOak for example.  How do I get
rid of the field name Habitat in the plot?
 
3> How do I tell the method to mark the significant comparisons? (i.e those
that do not intersect the zero line).
 
Thanks ../Murli

I finally determined the problem, but not the specific cause.

For some reason, the WMF is resized when saved or copied from R.  If you
compare the same plot pasted into PowerPoint as both a bitmap and a WMF, the
WMF has its height increased ~14% and its width decreased ~5% consistently. 
This is true whether you copy/paste or save the WMF.

At least, that is what occurs on my Windows XP machine with Office 2003 and
R 2.3.1 installed.
