[R] postscript problem

[Strumila, John]

I've had a similar problem when the gs_lib environment variable hasn't been
set up to point to the correct font libraries.  Check the man page for gs
and gv.

Subject: [R] postscript problem


hello all,
when trying to produce a plot with the following code

postscript("g6-5000-0705-b.ps")
par(mfrow=c(4,1))
for (i in 1:4) {
  somc<-cumsum(betaC[,i])/c(1:N)
  plot(somc,ylim=c(min(somc),max(somc)));
}
dev.off()

I get a postscript file g6-5000-0705-b.ps, but if I try to open it
with ghostscript, or to convert it to pdf, I get the following error :

Error: /invalidfont in findfont

Any idea of what's happening ?
