Description

Mapping of all habitat areas where the species is known to occur.

Usage

1
map.habitat(longlat, layer, polygon = TRUE, eval = TRUE)

Arguments

longlat

Matrix of longitude and latitude (two columns) of each occurrence record.

layer

RasterLayer object representing the presence/absence (1/0) of a single habitat type.

polygon

If TRUE, all habitat patches inside the minimum convex hull polygon encompassing all occurrence records are converted to presence.

eval

Build a matrix with EOO (from raw data), EOO (from model), AOO (from raw data) and AOO (from model).

Details

In many cases a species has a very restricted habitat and we generally know where it occurs. In such cases using the distribution of the habitat patches may be enough to map the species.

Value

One raster file and possibly a matrix with EOO (from raw data), EOO (from model), AOO (from raw data) and AOO (from model).
