In DSsim: Distance Sampling Simulations

Description

Class "Population.Description" is an S4 class containing a description of the population. It provides methods to generate an example population.

Slots

N

Object of class "numeric"; number of individuals in the population (optional).

density

Object of class "Density"; describes the population density

region.name

Object of class "character"; name of the region in which the population exists.

strata.names

Character vector giving the strata names for the study region.

covariates

Named list with one named entry per individual level covariate. Cluster sizes can be defined here. Each list entry will either be a data.frame containing 2 columns, the first the level (level) and the second the probability

size

logical value indicating whether the population occurs in clusters. (prob). The cluster size entry in the list must be named 'size'.

gen.by.N

Object of class "logical"; If TRUE N is fixed otherwise it is generated from a Poisson distribution.

D.dist

Object of class character; Describes the density distribution (currently not implemented).

Methods

get.N

signature=(object = "Population.Description"): returns the value of N
