Class "estUD": Storing Utilization Distributions in R
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 of class "estUD" can be created using the functions
kernelUD and getvolumeUD.
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
Class "SpatialPixelsDataFrame", directly.
signature(from = "estUD", to = "data.frame"):
converts the object into a data frame
signature(object = "estUD"): printing method of
the object

information about this class, and kernelUD for
additional information about the methods generating such objects.
## 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]])
