In letsR: Data Handling and Analysis in Macroecology

Create a matrix summarizing species' attributes within cells of a PresenceAbsence object

Description

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.
