## S4 method for signature 'telemetry'

## 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,...)

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

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

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

Confidence level of the UD area. I.e., the 50% core home range would be given by level.UD=0.50.

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.
