agwrite: Read / write Ragraph objects

In Rgraphviz: Provides plotting capabilities for R graph objects

Description

These functions will write an Ragraph object to or from a file.

Usage

agwrite(graph, filename)
agread(filename, layoutType="dot", layout=TRUE)

Arguments

graph	An object of class Ragraph
filename	The input or output filename
layoutType	character(1) specifying the format of the input file. must be one of graphvizCapabilities()$layoutTypes.
layout	logical(1) indicating whether graphLayout is to be called on the result of file input.

Details

file <- tempfile()
agwrite(z, file)


## supported input types
graphvizCapabilities()$layoutTypes
g2 <- agread(file, layout=TRUE)
