Invalid font in bitmap()
It's a problem in your ghostscript installation. Your example works in RH8.0, for example. (BTW, it is nowadays AFPL ghostscript 8.x or GNU ghostscript 7.03 or later.)

Dear all, A few weeks ago I asked about X11() availability using CGI-perl. The general advice was to use bitmap which requires ghostscript (Xvnc and Xvbf were the other alternatives). My system administrator got around to installing Aladin Ghostscript 6.0 and the setting the R_GSCMD environment variable. Other system specification is given below. But now I have a new problem that says that font is invalid and this is not even through the CGI-perl web mode. As per the 'Family' section of postscript I tried experimenting with the various options given but with the same problem. Here is an example ###### Code #######
x <- -10:10
bitmap("bitmaptest.png", family="URWGothic")
plot(x, x^2); title("A quadratic plot"); dev.off()
