load_graph {Diderot}

R Documentation

Function to load a citation graph

Description

This function loads a citation graph saved on the filesystem.

Usage

load_graph(filename)

Arguments

filename

File to load

Value

Returns a graph object.

Note

This function basically supports only graph previously saved with Diderot's save_graph. However, as the file is actually a graphml file handled by igraph, advanced users may use this function on appropriate graphs created elsewhere, as long as they respect Diderot's structure (presence of a "Corpus"" field, etc).
