Nodes overlap when layout="groups"

[desphua]

I tried to use layout="groups" but two nodes from different groups overlap each other (i.e., nodes 26 and 51 in my example below). How do I resolve this?

You can use the layout.control argument for this:

library("qgraph")
adj <- matrix(1,8,8)
groups <- rep(LETTERS[1:2],each=4)
qgraph(adj, groups = groups, layout = "circular", layout.control = 0.8)
