I previously posted about this problem on the r-help list, but was told
that I
should switch over to the r-sig-fedora list. So here goes:
When trying to do a plot in a certain context I got an error:
Error in text.default(2, 6, main, cex = cex) :
X11 font -adobe-helvetica-%s-%s-*-*-%d-*-*-*-*-*-*-*, face 1 at size
16 could not be loaded
This is reproducible (in my current environment) via:
par(mfrow=c(2,2))
plot(1:10)
text(2,6,"Oh, hell!",cex=2)
Can anyone tell me (in simple comprehensible terms, please) how I might
make the required font available so that it can be loaded? I reiterate,
please keep it simple. I find fonts toadally incomprehensible!
For what it's worth, here is my session info:

NOTE: In response to this query on r-help I received the suggestion that
I might need to install:
xorg-x11-font-utils
xorg-x11-fonts-75dpi
xorg-x11-fonts-100dpi
I had xorg-x11-fonts-utils installed already, as it turned out, but
managed to
install the other two packages via
sudo yum install xorg-x11-fonts-75dpi.noarch
sudo yum install xorg-x11-fonts-100dpi.noarch
After doing that things changed a *little* bit. Instead of an error I
got a warning:
> In text.default(2, 6, "Oh, hell!", cex = 2) :
> X11 used font size 25 when 28 was requested
and no actual characters appeared in the plot but rather 4 (???)
little rectangles outlined in dotted line type.
Any ideas as to how to alleviate *this* problem?
BTW my X11.options()$type is "Xlib". I tried setting it equal to
"cairo" but that
just made matters worse. Doing plot(1:10) in a fresh X11() device gave
the plot,
but with the axis labelling replaced by a few of those little
dotted-line rectangles.
Thanks for any insight and advice.
cheers,
