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
Proportional availability (for datasets without n2 and y2).
y1
A numeric vector: number of times the resource was used.
y2
A numeric vector: number of time the resource was observed.
n1
A numeric vector: number of times that all resources were used.
n2
A numeric vector: number of times that all resources were observed.
