Any dyad whose toggle would produce a nonzero change statistic
for a nodemix
term with the same arguments will be fixed. Note
that the levels2
argument has a different default value for
blocks
than it does for nodemix
.
# blocks(attr=NULL, levels=NULL, levels2=FALSE, b1levels=NULL, b2levels=NULL)
a vertex attribute specification (see Specifying Vertex attributes and Levels (?nodal_attributes
) for details.)
control what mixing types are fixed.
levels2
applies to all networks; levels
applies to unipartite networks;
b1levels
and b2levels
apply to bipartite networks (see Specifying Vertex
attributes and Levels (?nodal_attributes
) for details)
