R: Extent

extent {ctmm}

R Documentation

Extent

Description

Functions to calculate the (x,y) plotting extent (or bounding box) of various ctmm objects or list of such objects, for use when plotting multiple ctmm objects.

Usage


## S4 method for signature 'telemetry'
extent(x,level=1,...)

## S4 method for signature 'ctmm'
extent(x,level=0.95,level.UD=0.95,...)

## S4 method for signature 'UD'
extent(x,level=0.95,level.UD=0.95,complete=FALSE,...)

## S4 method for signature 'variogram'
extent(x,level=0.95,threshold=2,...)

## S4 method for signature 'list'
extent(x,...)

## S4 method for signature 'data.frame'
extent(x,level=1,...)

## S4 method for signature 'matrix'
extent(x,level=1,...)

Arguments

`x`	A `telemetry`, `ctmm`, or `UD` object.
`level`	For `telemetry` objects, this is the fraction of locations bounded, according to two-sided quantiles. For `ctmm` and `UD` objects, this is confidence level for the magnitude of the utilization area circumscribed by `level.UD`.
`level.UD`	Coverage level of the UD area. I.e., the 50% core home range would be given by `level.UD=0.50`.
`complete`	Also calculate longitude-latitude extent of `UD` objects.
`threshold`	Limit `ylim` to `threshold` times the maximum semi-variance, even if the `level` confidence intervals exceed this amount.
`...`	Optional arguments for future extensions.

Details

Returns a data.frame with columns x and y with rows min and max. See vignette('akde') for an example of extent used to plot multiple UDs on the same scale.
