graph: Graphs

In IBM/rflowgraph: Flow Graphs

Description

Generic interface for graphs as S3 objects (directed or undirected, simple or multi-edged).

Usage

is_directed(g)

nodes(g)

edges(g, ...)

nnodes(g)

nedges(g, ...)

add_node(g, node, ...)

add_nodes(g, nodes)

has_node(g, node)

rem_node(g, node)

add_edge(g, src, tgt, ...)

has_edge(g, src, tgt)

rem_edge(g, src, tgt, ...)

neighbors(g, node)

successors(g, node)

predecessors(g, node)

Details

Unlike most R objects, graphs are mutable and have pass-by-reference semantics.
