View source: R/red.R

Description

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

Usage

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

Arguments

longlat

Matrix of longitude and latitude or eastness and northness (two columns in this order) of each occurrence record.

layer

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

mcp

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

eval

If TRUE, 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 known habitat patches may be enough to map the species.

Value

One raster object and, if eval = TRUE, a matrix with EOO (from raw data), EOO (from model), AOO (from raw data) and AOO (from model).
