How to set fix node positions with ggnet2

I am using ggnet2 to visualize networks and I was wondering whether anyone is aware of a way to fix the node positions as it is possible with e.g. igraph (as explained e.g. here How to control the igraph plot layout with Fixed Positions?)

Thanks, Chris

Ok, this is an old question but in case anyone looks for the answer...

Make a matrix of the coordinates:

l = as.matrix(data.frame(x = c(0.1,0.1, 0.5, 0.8), y = c(0.75, 0.25, 0.5, 0.5)))

Use

ggnet2(net, mode = l)

I had the same problem myself and fixed it by setting the random seed. Apparently ggnet2 randomly distributes the nodes in line with the selected algorithm-mode. So to get reproducible that is to say identical plots just always use set.seed() before every plot.

e.g.:

set.seed(1)
ggnet2(net)
