Is it possible have vertex labels of variable font sizes.
labelling certain nodes with a bigger font size than others
g1 <- erdos.renyi.game(20, 2/20)
V(g1)$name<-letters[1:vcount(g1)]
plot(g1,vertex.label=V(g1)$name)
Understand there is a vertex.label.cex option in igraph.plot but it is global.
Yes it is possible.
V(g)$label.cexis what you’re after. See this blog post of mine for an example how: http://trinkerrstuff.wordpress.com/2012/06/30/igraph-and-sna-an-amateurs-dabbling/May I suggest next post you provide a reproducible example and you’ll likely get much better assistance.
