parSetFactory: Advanced control over JAGS on parallel workers

Description

JAGS modules contain factory objects for samplers, monitors, and random number generators for a JAGS model. These functions allow fine-grained control over which factories are active on parallel workers.

Usage

parListFactories(cl, type)
parSetFactory(cl, name, type, state)

Arguments

cl

a cluster object created by the snow package.

name

name of the factory to set

type

type of factory to query or set. Possible values are "sampler", "monitor", or "rng"

state

a logical. If TRUE then the factory will be active, otherwise the factory will become inactive.

Value

• parListFactories returns a data frame with two columns per each worker, the first column shows the names of the factory objects in the currently loaded modules, and the second column is a logical vector indicating whether the corresponding factory is active or not.

  sparStFactory is called to change the future behaviour of factory objects. If a factory is set to inactive then it will be skipped.
