Well it is some kind of font rendering problem. The default device is
the Cairo X11 device, which uses the Pango layout engine for font
rendering.

If you set the environment variable FC_DEBUG to 1 before launching your
R session, you will get some debugging information. It is very verbose,
but we only need to see this bit:

Hello.

I've got a new workstation running Fedora 10 linux and I use the KDE 4.2
desktop which uses some kind of new desktop environment called 'plasma'.

If I start up R and generate a plot (for example: hist(rnorm(10000,
mean=0,
sd=1), breaks=100) ). The plot appears but all text (the x/y axes, title,
etc..) is replaced by a square box. No font is rendered at all.

Has anyone else got this problem? If so do you have a work around or a
solution?

I'm using R version 2.8.1 installed from the Fedora 10 repositories if
that
helps.

Thanks in advance.

It sounds like you are missing some fonts. Check that the "urw-fonts" and
"liberation-fonts" RPMs are installed.

I checked with my KDE 4.2 (Mandriva 2009 system, kde.org binaries)
with no font rendering issues in running demo(graphics).

It is quite possible that pango was not installed with Fedora (as it
is unnecessary for KDE 4.2 systems). Installing the relevant rpm may
fix things.

The packaging of the Fedora 2.8.1 rpm may need to take this into
account - if compiling, you'd have discovered at configure stage.
