A Slick data object containing MSE results for the western Atlantic
skipjack tuna (Katsuwonus pelamis) used as a case study in Hordyk
et al. (in review). The object is derived from the WSKJ case study
available in the Slick App, with Boxplot, Quilt, Spider, and Tradeoff
slots populated from the Timeseries data to demonstrate all six plot
types supported by the package. Performance indicator values for the
additional plot types are summarized as means over the projection period
(years 2026–2055).
Format
An object of class Slick with all six plot slots populated: Timeseries, Kobe, Boxplot, Quilt, Spider, and Tradeoff.
