Datasets for resource use and availability

Description

A collection of datasets which can be used to calculate and compare selection ratios. Datasets are: goat.sel, mule.sel, quail.sel, elk.sel, bighorn.sel, bighornAZ.sel, juniper.sel and are described (briefly) in Manly et al. (2002) and Aho and Bowyer (2015).

Format

Dataframes with observations on the following variables.

resources

A factor listing resource types.

avail

y1

A numeric vector: number of times the resource was used.

y2

A numeric vector: number of time the resource was observed.
