Read and write BIF, NET, DSC and DOT files

Description

Read networks saved from other programs into bn.fit objects, and dump bn and bn.fit objects into files for other programs to read.

Usage

# Old (non-XML) Bayesian Interchange format.
read.bif(file, debug = FALSE)
write.bif(file, fitted)

# Microsoft Interchange format.
read.dsc(file, debug = FALSE)
write.dsc(file, fitted)

# HUGIN flat network format.
read.net(file, debug = FALSE)
write.net(file, fitted)

# Graphviz DOT format.
write.dot(file, graph)

Arguments

file

a connection object or a character string.

fitted

an object of class bn.fit.

graph

an object of class bn or bn.fit.

debug

a boolean value. If TRUE a lot of debugging output is printed; otherwise the function is completely silent.

Value

read.bif(), read.dsc() and read.net() return an object of class bn.fit.

write.bif(), write.dsc(), write.net() and write.dot() return NULL invisibly.

Note

All the networks present in the Bayesian Network Repository have associated BIF, DSC and NET files that can be imported with read.bif(), read.dsc() and read.net().

HUGIN can import and export NET files; Netica can read (but not write) DSC files; and GeNIe can read and write both DSC and NET files.

DOT files can be read by Graphviz, Gephi and a variety of other programs.

Please note that these functions work on a "best effort" basis, as the parsing of these formats have been implemented by reverse engineering the file format from publicly available examples.
