[R] Invalid font in bitmap()

[Adaikalavan Ramasamy]

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()
Error: /invalidfont in findfont
