propagate.gRaven {gRaven}

Propagate method for a gRaven domain

Description

Propagate method for a gRaven domain

Usage

## S3 method for class 'gRaven'
propagate(object, ...)

Arguments

object

character string, name of gRaven domain

...

additional arguments to propagate

Details

Propagates all previously entered evidence through the network. This call is required by functions such as get.belief and map.configurations, but not before get.normalization.constant. In the implementation, findings will have been accumulated in the variable net$cache in the domain, by calls to set.finding, and are moved to net$evid by the propagate function.

Value

a NULL value is invisibly returned.
