This term adds one network statistic for each node equal to the number of
ties of that node. For directed networks, see sender
and
receiver
.

this optional argument is deprecated and will be replaced with a more elegant implementation in a future release. In the meantime, it specifies a categorical vertex attribute (see Specifying Vertex attributes and Levels (?nodal_attributes
) for details). If provided, this term only counts ties between nodes with the same value of the attribute (an actor-specific version of the nodematch
term), restricted to be one of the values specified by (also deprecated) levels
if levels
is not NULL
.
deprecated
By default, nodes=-1
means that the statistic for the
first node will be omitted, but this argument may be changed to control
which statistics are included just as for the nodes
argument of sender
and
receiver
terms.
