I would like to lay out graphs (trees) with two types of nodes: boxes and circles.
Is this possible with igraph and how would a minimal example look like?

A:
library(igraph)
g <- graph.empty()
g <- add.vertices(g, 4,
label=c('a', 'b', 'c', 'd'),
shape=c('rectangle', 'rectangle', 'circle', 'circle'))
g <- add.edges(g, c(1, 2, 2, 3))
plot(g)

just for reference, I found out that "color" is one more attribute to add.vertices that sets the background color.

And "size" seems to be another, however I did not find out how it works for rectangles.
