R: Asymmetric dyads

asymmetric-ergmTerm {ergm} | R Documentation

## Asymmetric dyads

### Description

This term adds one network statistic to the model equal to the number of pairs of actors for which exactly one of (i,j) or (j,i) exists.

### Usage

    # binary: asymmetric(attr=NULL, diff=FALSE, keep=NULL, levels=NULL)

### Arguments

`attr` | quantitative attribute (see Specifying Vertex attributes and Levels (`?nodal_attributes`) for details.) If specified, only symmetric pairs that match on the vertex attribute are counted.
`diff` | Used in the same way as for the `nodematch` term. (See `nodematch` (`?nodematch`) for details.)
`keep` | deprecated
`level` | Used in the same way as for the `nodematch` term. (See `nodematch` (`?nodematch`) for details.)

### Note

This term can only be used with directed networks.

The argument `keep` is retained for backwards compatibility and may be removed in a future version. When both `keep` and `levels` are passed, `levels` overrides `keep`.
