conregmat: Connected regions per species

In prabclus: Functions for Clustering and Testing of Presence-Absence, Abundance and Multilocus Genetic Data

Connected regions per species

Description

Returns a vector of the numbers of connected regions per species for a presence-absence matrix.

Usage

con.regmat(regmat, neighbors, count = FALSE)

Arguments

regmat	0-1-matrix. Columns are species, rows are regions.
neighbors	A list with a component for every region. The components are vectors of integers indicating neighboring regions. A region without neighbors (e.g., an island) should be assigned a list numeric(0).
count	logical. If TRUE, the number of the currently processed species is printed.

Details
