is.durational {ergm}R Documentation

Testing for durational dependent models

Description

These functions test whether an ERGM model or formula is durational dependent or not. If the formula or model does not include any terms that need information about the duration of existing ties, the ergm proceass can use more efficient internal data structures.

Usage

## S3 method for class 'character'
is.durational(object, ...)
## S3 method for class 'ergm.model'
is.durational(object, ...)
## S3 method for class 'formula'
is.durational(object, 
                                      response=NULL,
                                      basis=NULL,
                                      ...)

Arguments

object

An ergm object or an ERGM formula, or some characters, e.g., object="all" for monitoring purpose.

response, basis

See ergm.

Unused at this time.

Value

TRUE if the ERGM terms in the formula or model are durational dependent ; FALSE otherwise.
