SpNaBaMatrix-class: Class SpNaBaMatrix

In edelcallejoc/rspecies: A Spatial Data Mining Framework for Species Distribution Modelling

Description

SpNaBaMatrix is used to fit Spatial Naive Bayes models. It can be used to extract information of the sample and to adjust Spatial Naive Bayes models.

Usage

SpNaBaMatrix(freqmatrix, ...)

Arguments

freqmatrix	matrix. typically, the output of id_pts() function. See slots section for more details.
...	argument pass to other methods.

Value

An object of class SpNaBaMatrix. See slot section for more details.

Slots

freqmatrix

matrix. A matrix with $N$ rows (rows correspond to the number of blocks in the GRID) and $M$ columns (columns represent the number of factors included in the model), where each element $i,j$ shows the number of observations of the factor $j$ in the cell $i$.

binmatrix

matrix. A matrix with $N$ rows (rows correspond to the number of blocks in the GRID) and $M$ columns (columns represent the number of factors included in the model), where each element $i,j$ shows TRUE if the cell $i$ contains at least one observation of the factor $j$. FALSE otherwise.

a <- matrix(rbinom(100, 100, runif(100)), nrow = 10, ncol = 10,
  dimnames = list(paste0("id:", 1:10), letters[1:10]))

# Loading data
