[R] X11 font problem

Dear R users,

I've just upgraded from R 0.64.1 to 1.1.0 on a PC running Red Hat Linux
6.0.  When I ran demo(graphics), after the command:

title(main = "January Pie Sales", cex.main = 1.8, font.main = 1)

the plot did not materialise and I received this error message: 

Error in title(main = "January Pie Sales", cex.main = 1.8, font.main = 1)
: X11 font at size 22 could not be loaded

similarly, when I enter the following commands

> testdata <- read.table("test.dat", header=T)
> pairs(testdata)

I get the following response:

Hit <Return> to see next plot: 
Error in text.default(x, y, txt, cex = cex, font = font) : 
	X11 font at size 16 could not be loaded
In addition: Warning message: 
freeing previous text buffer in GStrWidth 

These errors did not occur in my previous version of R.  Looking at the
files ONEWS and NEWS that came with the 1.0.0 and 1.1.0 releases
respectively, I notice that a great deal has changed with X11 font
handling in R since version 0.64.1.  I confess that I am still rather
inexperienced in the R system and so don't know whether these errors are
because of R, my Linux setup or some combination of the two.

Any comments and/or advice would be gratefully received.
