Load and save Hugin net files

These functions can load a net file saved in the 'Hugin format' into R and save a network in R as a file in the 'Hugin format'.

loadHuginNet(file, description = NULL, details = 0)

saveHuginNet(gin, file, details = 0)

Arguments

file

Name of Hugin net file. Convenient to give the file the extension '.net'

description

A text describing the network, defaults to file

details

Debugging information.

gin

An independence network

Value

An object of class grain.

Note

• In Hugin, it is possible to specify the potential of a node as a functional relation between other nodes. In a .net file, such a specification will appear as 'function' rather than as 'node'. Such a specification is not recognized by loadHuginNet.

• It is recommended to avoid the text node as part of the name of a node.

Examples

## Load HUGIN net file
tf <- system.file("huginex", "chest_clinic.net", package = "gRain")
chest <- loadHuginNet(tf, details=1)
chest 
#> Independence network: Compiled: TRUE Propagated: FALSE Evidence: FALSE 

## Save a copy
td <- tempdir()
saveHuginNet(chest, paste(td,"/chest.net",sep=''))

## Load the copy
chest2 <- loadHuginNet(paste(td,"/chest.net",sep=''))

tf <- system.file("huginex", "golf.net", package = "gRain")
golf <- loadHuginNet(tf, details=1)

saveHuginNet(golf, paste(td,"/golf.net",sep=''))
golf2 <- loadHuginNet(paste(td,"/golf.net",sep=''))
