Dear Rgraphviz-experts, I am trying to adjust the fontsize of graph nodes in a plot produced by the Rgraphviz package. However, any fontsize related changes I make don't have an effect when I plot the graph. For example code 1 below generates a random graph with 4 nodes. In order to make the fontsize of the graph nodes smaller than normal, I tried to adjust the attrs variable as shown in code 2, but after plotting the graph I still notice no change in terms of fontsize. All other node attributes work except for fontsize. I don't know if this is expected in general or I made a mistake. Many thanks for any help! Cheers, Claudio code1: library("Rgraphviz") set.seed(123) V <- LETTERS[1:4] M <- 1:4 g1 <- randomGraph(V, M, 0.2) plot(g1) code2: globA=list(node=list(fontsize="6"),edge=list(minlen="3")) plot(g1,attrs=globA)
