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.

Yes, par(family="mono") would work, except that I get R segfaults from this

plot.new()
par(family="mono")
par(cex=8)
strheight("foo")
Process R segmentation fault (core dumped) at Mon Dec 20 16:07:56 2004
on R 2.0.1 (2004-11-15), Red Hat Enterprise Linux AS release 3
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
