R help - Apr 2012 - A trivial plot gives open circles as the plot char but another one gives me "q"s . . why is this?

People,

On my home computer with a real plot I get what I expect - open circles 
as the plot character - on my work computer I get "q"s !  So I tried a
trivial test plot on the work computer ie:

  a <- c(1,2,3,4,5)
  b <- c(1,2,3,4,5)
  plot(a,b)

and that also gives me open circles as it should! - the plot line in my 
real script is:

  plot( means5[ ,4 ], means6[ ,4 ], xlab="640loci-50reps Gen4(-1)
Rst",
ylab="ADf" )

I have tried adding the "pch=x" command with no effect . . what is 
going on?  (Both computers have the same fonts installed although the 
home computer is Fedora 16 and the work one is Fedora 15).  It is very 
frustrating . .

Thanks,

Phil.

Argh. I have forgotten this before... There was a configuration issue leading to
plotting symbols showing up as "q", but I can't recall the
details. Possibly libpango-related (do you have it installed?)

Did you actually type pch=x  ?

Not pch="x" ?

Sorry, I meant x as in 1,2,3, . . . 18
