I know this is possible in Statistica but can't seem to find out if its possible in R. The main reason I want to print only half the plots is the hope that is will significantly speed up generating the matrix plot. If anyone has any ideas to how this could be achieved, I very much appreciate a response.

So you are talking about package car?
Why is this related to mailing list gr? I think this would have been a 
better question for R-help, or whatever ....

Use argument "upper.panel", which is passed down to pairs(), as follows:

scatterplot.matrix(~income + education + prestige | type, data=Duncan,
     upper.panel=NULL)
