# S4 method for IntervalMatrix
as_graph(from)

# S4 method for StratigraphicMatrix
as_graph(from)

Arguments

from: A square adjacency matrix (typically an AdjacencyMatrix object).

Methods (by class)

as_graph(IntervalMatrix): Produces an interval graph.
as_graph(StratigraphicMatrix): Produces a stratigraphic graph.

Interval Graph

An interval graph is the graph showing intersecting intervals on a line. As time is linear and not circular, an interval graph contains no cycles with more than three edges and no shortcuts.
