Converts a network object (unipartite) to a
two-mode (bipartite) network representation.
Usage
as.bipartite(x, y)
Arguments
x
A network object.
y
A vector of membership values.
Value
Returns a matrix with the species of one mode arrayed
in rows and the other in columns.
Details
Bipartite network approaches are often used for analyzing
the structure of interactions among species in communities.
Although typically ecosystem networks are handled using a unipartite
representation, anlayzing them from a bipartite perspective may
be informative. This function provides an easy means for converting to
a bipartite representation as long as there is a natural division
to categorize species into distinct modes.
