Vincent, you need to include the fonts to be used in the 'postscript'
call, otherwise only 'Helvetica' is available. Unfortunately for igraph
the default is 'serif', hence the error message. Here is how to do it,
the trick is the 'fonts' argument of 'postscript':
g <- graph.ring(10)
E(g)$label <- sample(letters, ecount(g))
postscript("/tmp/test.eps", fonts=c("serif", "Palatino"))
plot(g, layout=layout.circle, vertex.label.family="serif",
edge.label.family="Palatino", vertex.label.cex=2,
edge.label.cex=2)
dev.off()
Of course in this case 'vertex.label.family ' could be omitted as
the default is 'serif' anyway.
Another solution would be to set the default font to 'serif' with
ps.options.
Best,
Gabor
