[R] screen resolution effects on graphics

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.
