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.
The X11 device works pretty hard to find a font to use and if it really can't find anything it should throw an error, not segfault. Are you able to debug this and see where it is failing?
(I'm using Xwin32 and for large font size requests that can't be satisfied I get the intended behaviour which is warnings that a smaller font is being substituted)

[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.

In my code I call strheight and strwidth several times in
order to find a
cex that makes the text best fit the display area. Once
the segfaulting is
fixed, I'll update my code to use par(family="mono").

This is neat Greg. Just installed the latest gregmisc. Do you automatically used fixed width fonts for this, for alignment of columns?
Unfortunately, I haven't found any way to select
fixed-width fonts, so I
convert the character vector into a matrix of individual
characters so that
they align properly. Its pretty horrid.
I hope that the R developers will provide a way of
selecting a fixed width
font in the future so I can remove this ugly hack.
Does par(family="mono") do what you want?
Paul
It works here using R 2.0.1 under FC3. I tried it to the
display and
with pdf() using sinkplot().
With postscript() one can use the 'family = "Courier' argument as well. Seems to work here.
According to ONEWS, par("family") is new for 2.0.0.
Missed that one.
Thanks Paul.
Marc
