Thanks for the solution to the above problem. I am facing another
problem which seems to stem from the one above. After getting my plot on
screen I do 
dev.copy(png, file="out.png") 
dev.off()

The resultant PNG file shows the plots ok, but the ends of the overall
title get cut off. I tried changing the values in the oma vector tp par,
but it does'nt change anything.

Has anybody faced this?

Thanks,
