From sessionInfo()

R version 2.11.1 (2010-05-31) 
i386-apple-darwin9.8.0 

locale:
[1] en_US.UTF-8/en_US.UTF-8/C/C/en_US.UTF-8/en_US.UTF-8

attached base packages:
[1] stats     graphics  grDevices utils     datasets  methods   base     

loaded via a namespace (and not attached):
[1] tools_2.11.1


demo(plotmath) produces a table of equations loaded with sigmas and pi's, alphas, omicrons, subsets, supersets, upsilons, etc...

I'm not sure what demo you're running quite frankly.

How else do you want me to "expound on my difficulties"? I've said as straightforwardly as I can what is happening. My newsgroup client doesn't allow me to post images to this newsgroup, so it is difficult for me to show you what I mean, so if you've run demo(plotmath) you should know which fonts I am referring to.

For most men life is a search for the proper manila envelope in which to get themselves filed.
