Re: [igraph] Questions about decompose.graph?[can not support translucent when save figures as ps, pdf or tiff ]

[Gábor Csárdi]

This is definitely device dependent, and might be even operating
system dependent. E.g. exporting it to a PDF works fine for me in OS
X:

g <- graph.ring(10)
pdf("/tmp/a.pdf")
plot(g, mark.groups=list( c(1:5), c(5:10) ) )
dev.off()

You need to use an R graphics device that supports it. Probably try PDF first.
