mono fonts (was RE: [Rd] RE: [R] SAS or R software)

[Warnes, Gregory R]

Ah, I'm using Exceed Hummingbird 7.1 as the X server....  

It does have fixed width fonts, and it is happy with variable width fonts up
to this extreme ....

A little more fiddling shows that this succeds with a linux based X11
server, and that even 
	plot(1,1)
	par(family="mono",cex=8)
	text(1,1,"foo") 
segfaults.


I've tested values of cex.  Anything above 2.1249 seems to segfault.
