Catch Advice for Fisheries Managed by Harvest Slot Limits R package SlotLim version 0.0.2 Catch advice for data-limited vertebrate and invertebrate fisheries managed by harvest slot limits using the SlotLim harvest control rule. The package accompanies the manuscript "SlotLim: catch advice for data-limited vertebrate and invertebrate fisheries managed by harvest slot limits" (Pritchard et al., in prep). Minimum data requirements: at least two consecutive years of catch data, length–frequency distributions, and biomass or abundance indices (all from fishery-dependent sources); species-specific growth rate parameters (either von Bertalanffy, Gompertz, or Schnute); and either the natural mortality rate ('M') or the maximum observed age ('tmax'), from which M is estimated. The following functions have optional plotting capabilities that require 'ggplot2' installed: prop_target(), TBA(), SAM(), catch_advice(), catch_adjust(), and slotlim_once(). Software Imports: ggplot2, grid, stats, utils, patchwork Suggests: testthat (>= 3.0.0) C.J. Pritchard <cj_pritchard@outlook.com> Comprehensive R Archive Network (CRAN) C.J.
