Success! (Sort of) Running outside R in the DOS window produces
C:\Program Files\R\R-2.3.1\bin>cscript displayconfiguration.vbs
Microsoft (R) Windows Script Host Version 5.6
Copyright (C) Microsoft Corporation 1996-2001. All rights reserved.
Name: NVIDIA GeForce FX 5200
Color depth: 32
Horizontal resolution: 1280
Vertical resolution: 1024
I don't have immediate access to a machine with 800X600 native resolution so
I can't compare.
What's next?
The problem isn't that a jpg produced on this machine looks crowed on an 800
X 600 machine. It's that the same R code on this machine generates a
crowded jpeg on the older machine. My hope was to check the capability of
the current machine and make some modest adjustments to my R code to produce
an acceptable jpg on any machine running it.
Thanks.

This is what happens when I run it in R 2.3.1:
> as.numeric(gsub(".* ", "", grep("resolution",
+ shell('cscript \\bin\\displayconfiguration.vbs', intern = TRUE),
+ value = TRUE)))
[1] 1280 1024
The result is obviously dependent on your particular video
card (I have a radeon). Try running it from outside of R and see
what you get:
cd \bin
cscript displayconfiguration.vbs
Also make sure you copied the code correctly from the web site
and also try the second solution too just in case.
Its possible that virus detection software will interfere since some
antivirus programs prevent all vbscript routines from running.
