homerange: Calculate a range distribution estimate

In ctmm-initiative/ctmm: Continuous-Time Movement Modeling

Calculate a range distribution estimate

Description

Estimates the range distributions and suitability from telemetry data and a continuous-time movement model.

Usage

homerange(data,CTMM,method="AKDE",...)

agde(data=NULL,CTMM=NULL,R=list(),variable="utilization",error=0.001,res=100,grid=NULL,
     ...)

suitability(data=NULL,CTMM=NULL,R=list(),level=0.95,grid=NULL,log=FALSE,...)

Arguments

data	2D timeseries telemetry data represented as a telemetry object.
CTMM	A ctmm movement model from the output of ctmm.fit.
method	Which range distribution method to use. Can be "AKDE" or "AGDE".
...	Arguments passed to the method call or bandwidth.
R	A named list of raster covariates if CTMM contains an RSF model
variable	Not yet supported.
error	Target probability error.
res	Number of grid points along each axis, relative to the location covariance.
grid	Grid specification via raster, UD, or list of arguments (See akde for details).
level	Confidence level for output confidence intervals.
log	Calculate the log(suitability).

Details

homerange is a wrapper function that calls either akde or agde. Please consult akde for further details on method="AKDE".

suitability calculates a suitability raster from an rsf.fit object. Population RSF fit objects calculated from mean will produce a suitability estimate of the population.

agde calculates autocorrelated Gaussian and RSF home-range areas.

Value

homerange and agde return a UD object. suitability returns a brick object.
