estUD-class: Class "estUD": Storing Utilization Distributions in R

Description Objects from the Class Slots Extends Methods Author(s) See Also Examples

Description

This class is an extension of the class SpatialPixelsDataFrame of the package sp, and is designed to store the utilization distribution of an animal

Objects from the Class

Objects of class "estUD" can be created using the functions kernelUD and getvolumeUD.

Slots

h:

Object of class "list" containing all information concerning the smoothing parameters used in the estimation process

vol:

Object of class "logical" indicating whether the mapped values coorespond to the UD or to the volume under the UD (see ?kernelUD)

data:

Object of class "data.frame" containing the values of the UD

Extends

Class "SpatialPixelsDataFrame", directly.

Methods

coerce

signature(from = "estUD", to = "data.frame"): converts the object into a data frame

show

signature(object = "estUD"): printing method of the object

## load the data
data(puechabonsp)

## estimate one UD for each animal
jj <- kernelUD(puechabonsp$relocs[,1])
image(jj)
jj


## Consider the first animal
jj[[1]]
class(jj[[1]])
image(jj[[1]])
