R: Connected regions per species

con.regmat {prabclus} | R Documentation

## 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

Uses `con.comp`.

### Value

Vector of numbers of connected regions per species.

### Note

Designed for use in `prabtest`.
