blocks-ergmConstraint {ergm}

Constrain blocks of dyads defined by mixing type on a vertex attribute.

Description

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.

Usage

# blocks(attr=NULL, levels=NULL, levels2=FALSE, b1levels=NULL, b2levels=NULL)

Arguments

attr

a vertex attribute specification (see Specifying Vertex attributes and Levels (?nodal_attributes) for details.)

b1levels, b2levels, levels, level2

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)
