[R] hold position of vertices constant in network {statnet}?

[Matt Bakker]

I am a novice with network fuctions! I have been exploring the network
function in the statnet package, but haven't been able to figure out
how to hold vertices in position while varying edge features. Can
anyone advise on whether this is possible, and if so, how to do it?
Thanks!
