|
raster |
A RasterLayer (single projection) or RasterStack (multiple projections) object containing ENM projection(s) with suitability scores. |
threshold |
Suitability value(s) below which all values are converted into zeros. If a RasterStack (multiple projections) is used, the argument should contain a vector of threshold values. |
qvalue |
A positive number, usually between 0 and 5, but most commonly 0, 1 or 2. It can be an integer or contain decimals. |
relative |
Whether to compute absolute or relative breadths. Default=FALSE |
Convert raster(s) into cell vector or matrix
A single or multiple spatial breadth measures.
