popn: Population Object
In secr: Spatially Explicit Capture-Recapture
popn R Documentation
Population Object
Description
Encapsulate the locations of a set of individual animals.
Details
An object of class popn records the locations of a set of
individuals, together with ancillary data such as their sex. Often used
for a realisation of a spatial point process (e.g. homogeneous Poisson)
with known density (intensity). Locations are stored in a data frame
with columns ‘x’ and ‘y’.
A popn object has attributes
covariates data frame with numeric, factor or character variables to be used as individual covariates
model2D 2-D distribution ("poisson", "cluster", "IHP", "linear" etc.)
Ndist distribution of number of individuals ("poisson", "fixed")
boundingbox data frame of 4 rows, the vertices of the rectangular area
The number of rows in covariates must match the length of
x and y. See sim.popn for more information
on Ndist and model2D.
Note
The popn class is used only occasionally: it is not central to spatially explicit capture recapture.
