summary.UD: Summarize a range distribution

Description

This function returns a list of biologically interesting parameters in human readable format, as derived from an autocorrelated kernel density estimate.

Usage

## S3 method for class 'UD':
summary(object,level.UD=0.95,level=0.95,...)

Arguments

object

An akde autocorrelated kernel-density estimate from the output of akde.

level.UD

Confidence level for the home-range area. E.g., the 50% core area.

level

Confidence level for the above area estimate. E.g., the 95% confidence interval of the 50% core area.

...

Unused options.

Value

• A matrix with low, maximum likelihood, and high estimates for the following parameters: [object Object]
