This term adds one statistic to the model, equal to the sum
of the covariate values for each edge appearing in the network. The
edgecov term applies to both directed and undirected networks. For
undirected networks the covariates are also assumed to be undirected. The
edgecov and dyadcov terms are equivalent for undirected
networks.
# binary: edgecov(x, attrname=NULL)# valued: edgecov(x, attrname=NULL, form="sum")
either a square matrix of covariates, one for
each possible edge in the network, the name of a network
attribute of covariates, or a network; if the latter, or if the
network attribute named by x is itself a network, optional
argument attrname provides the name of the quantitative edge
attribute to use for covariate values (in this case, missing
edges in x are assigned a covariate value of zero).
