R: Constrain "blocks" of dyads

blocks-ergmConstraint {ergm} | R Documentation

## Constrain "blocks" of dyads

### 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` | quantitative attribute (see Specifying Vertex attributes and Levels (`?nodal_attributes`) for details.)
`b1levels, b2levels, levels, level2` | control what statistics are included in the model and the order in which they appear. `levels2` apply 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)
