Hello all!
I'm a newcomer to R, so please bear with me. My problem is the
following:
I'm trying to use R to do some geostatistics stuff (mostly kriging), and
am having trouble printing a multiple figure. When I create a single
figure (one image/contour command), it works fine. The instant I try to
create a multiple figure file, I start getting postscript errors. I'm
using the 0.90 version of R for linux.
Here are the commands I have been using:
postscript("crocheinterp.ps", family="Times", height=7,
width=4, horizontal=FALSE, paper="letter")
par(mfcol=c(2,2))
par(mfg=c(1,1,2,2))
par(mai=c(0.5, 0.5, 0.5, 0.5))
plot(croche.day.epi.grid$xy, type="n", xlim=c(0,100),
ylim=c(0,200), xlab="", ylab="")
image(croche.day.epi.grid$x, croche.day.epi.grid$y,
matrix(croche.day.epi.grid$krige$zhat,
length(croche.day.epi.grid$x), length(croche.day.epi.grid$y)),
add=T, col=grays)
contour(croche.day.epi.grid$x, croche.day.epi.grid$y,
matrix(croche.day.epi.grid$krige$zhat,
length(croche.day.epi.grid$x), length(croche.day.epi.grid$y)),
add=T)
par(mfg=c(2,1,2,2))
par(mai=c(0.5, 0.5, 0.5, 0.5))
etc., etc., etc.
When I try to open the crocheinterp.ps file, ghostview gives me the
following error:
Error: /invalidfont in findfont

Now, I know next to nothing about postscript errors, so I can't quite
figure this out. Does anyone have any ideas?
Thanks in advance
