We've only switched from redhat 7.3 to 9 several weeks ago, and
I found today, that the last three pages
of
demo(plotmath)
uses quite wrong plot symbols, e.g
sum(....) gives (+) {+ in circle} instead of the Sigma-like
summation --- but only in "text" not in title, i.e., probably a
font problem.
With postscript() {and hence dev.print() of x11()} all is fine.
Hence it must be an X font server problem of some kind.
Here is a reproducible example:xsum <- expression(sum(x[i], i = 1, n)) plot(1.1, main=xsum, xlab=xsum, ylab=xsum) text(1,1,xsum) which produces the graphic that I attach. If you can try this yourself _and_ if you see the same effect, could you tell me (or us) what OS / setup / ... you are using? Could R try better to get proper X11 fonts?
