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

[Prof Brian Ripley]

[Please update the subject line, folks!]

We need to know the device in use here ... and only a few support this 
mechanism.

If it is X11(), I suspect the problem is in what fonts are available, 
since cex=8 is pretty extreme.  So most likely you need to contribute a 
patch based on debugging on your system.

BTW, for those who missed this, see Paul's article in the Sept 2004 
R-News.

BTW^2 some devices have supported fixed-width fonts for many years.
