[R] Changing shapes of some Nodes

[lpupp]

Hi,

I am using the "igraph" package to plot a network. I need most of the
vertices to be green and circular. A few selected vertices I need to change
to make them blue squares.

I created this loop to color the necessary nodes blue but I dont know how to
change their shapes:

for(i in projectionV.node) {
	base.net.node <- set.vertex.attribute(base.net.node, name="color",
index=which(V(base.net)$name==i), value=blue.color)
}

help is much appreciated!
