Examples

# Using the function id_pts() for spatial data --------

library(sp)
library(rgeos)
library(rgdal)
library(raster)

# Loading data
data(Mex0)
data(mammals)

# Generating de grid from Mex0 data
Mex0.grd<-grd_build(Mex0)

# Identification points of mammals
x.mat<-id_pts(grd = Mex0.grd, pts = mammals)

# Without target declaration --------------------------

system.time(x.counts <- counts(x.mat))

# With target declaration -----------------------------

x.counts <- counts(x.mat, target = 1:10)

# Probability matrices -----------------------------------
x.probs <- probs(x.counts, fac.lap = 0.1)

# Score parameter -----------------------------------

x.score <- score(x.probs)
