print.mathgraph: Print a Mathematical Graph

In ClausDethlefsen/mathgraph: Directed and Undirected Graphs

Description

Prints a representation of the graph.

Usage

## S3 method for class 'mathgraph'
print(x, prefix.node = if (is.character(xu)) "" else "node", ...)

Arguments

x	an object inheriting from mathgraph which represents a mathematical graph.
prefix.node	a string to put in front of each node named. The default is an empty string if the nodes are character and the string "node" if they are not.
...	other arguments to print may be given, but are not used.

Details

The object is printed.
A ‘–’ between nodes means an undirected edge, while a single arrow means a directed edge.

Value

the input x is returned invisibly.

Note

The format is consistent with the dot graph language.
