An internal function to generate a new network object using the output (lists of toggled heads and tail vertices) from an ergm MCMC or SAN process.
newnw.extract(oldnw, z, output = "network", response = NULL)a network object (presumably input to the ergm process) from which the network- and vertex-level attributes will be copied
a list having either a component named newedgelist or two components newtails and newheads containing the ids of the head and tails vertices of the edges. Optionall newweights containing edgewights.
passed to network.update, which claims not to use it
optional character string giving the name of the edge attribute where the edge values (weight/count) should be stored.
a network object with properties copied from oldnw and edges corresponding to the lists of tails and head vertex ids in z
