mink: American mink _Neovison vison_ data.

In jaroyle/oSCR: Multi-Session Sex-Structured Spatial Capture-Recapture Models

American mink Neovison vison data.

Description

The mink data is the data analyzed by Fuller et al. (2016) in their Ecological Applications paper, with 2 objects illustrating fitted models.

Usage

data("mink")

Format

The data include 5 lists, mink.sf (scrFrame), mink.cs (cost surface), mink.ss (state-space object), Mecol (ecological distance model fit object; see Examples), and mEuc (Euclidean distance model fit object; see Examples).
