rhrArea: Area of a home-range estimate

In jmsigner/rhr: Reproducible Home Ranges with R

Description

rhrArea returns the area of a home-range estimate.

Usage

rhrArea(x, ...)

Arguments

x	Instance of RhrEst.
...	None implemented.

Details

For geometric estimators the isopleth levels at which the area is calculated is already determined when the estimate is performed. Probabilistic estimators take an additional argument, levels, that determines at which isopleth level of the UD the area is evaluated.

Value

data.frame with the isopleth level and area in units of the coordinate system.

Examples

data(datSH)

# Geometric estimator
mcp <- rhrMCP(datSH[, 2:3])
rhrArea(mcp)

mcp <- rhrMCP(datSH[, 2:3], levels = seq(50, 95, 5))
rhrArea(mcp)

# Note the levels argument does not change anything for geometric 
# estimators such mcp
rhrArea(mcp, levels = 44)


## Probabilistic estimator
kde <- rhrKDE(datSH[, 2:3])
rhrArea(kde)

## at a different isopleth level
rhrArea(kde, levels = 50)

## or at sequence of isopleth levels
rhrArea(kde, level = seq(50, 95, 5))
