graph-class {MPSEM}

Class and Method for Directed Graphs

Description

Class and methods to handle graphs.

Usage

## S3 method for class 'graph'
print(x, ...)

Arguments

x

An object of graph-class.

...

Additional parameters to be passed to the method. Currently ignored.

Format

A graph-class object contains:

edge

A list whose first two unnamed members are the indices of the origin and destination vertices. Additional members must be named and are additional edge properties (e.g. length).

vertex

A list that optionally contain vertex properties, if any (or an empty list if none).

Details

Prints user-relevant information about the graph: number of edges and vertices, edge and vertex labels, addition edge properties and vertex properties.

Functions
