Create a matrix summarizing species' attributes within cells of a PresenceAbsence object — lets.maplizer • letsR

Summarize species atributes per cell in a presence-absence matrix.

Usage

lets.maplizer(x, y, z, func = mean, ras = FALSE)

Arguments

x: A PresenceAbsence object.
y: Species attribute to be considered. It must be a numeric attribute.
z: Species names in the same order as the attributes and exactly the same as named in the PresenceAbsence object.
func: A function to summarize the species' atribute in each cell (the function must return only one value).
ras: If TRUE the raster object will be returned together with the matrix.

Value

The result can be both a matrix or a list cointaining the follow objects:

Matrix: a matrix object with the cells' geographic coordinates and the summarized species' attributes within them.

Raster: The summarized species'attributed maped in a SpatRaster object.
