Extract results

Description

Extract results from CaribouHabitat or DisturbanceMetrics object.

Usage

results(x, ...)

## S4 method for signature 'CaribouHabitat'
results(x, type = "both")

## S4 method for signature 'DisturbanceMetrics'
results(x, type = "disturbanceMetrics")

Arguments

x	A CaribouHabitat or DisturbanceMetrics object.
...	arguments passed to methods
type	string. The name of the slot to return. If x is a CaribouHabitat object the default is "both" and the habitatUse and processedData will be returned as a RasterStack.

Value

By default a RasterStack if x is a CaribouHabitat object and a data.frame if x is a DisturbanceMetrics object.
