Statistical Catch-at-Age Plotting Environment

Description

Import and plot results from statistical catch-at-age models, used in fisheries stock assessments.

Details

Import model results:

importADCAM ADCAM model results
importCol Coleraine model results

Plot model fit to data:

plotCA catch at age
plotCL catch at length
plotIndex abundance index
plotLA length at age

Plot derived quantities:

plotB biomass, recruitment, and landings
plotN numbers at age
plotSel selectivity and maturity

Sigmas and sample sizes:

getN, getSigmaI, getSigmaR extract
estN, estSigmaI, estSigmaR estimate
iterate combine all get* and est*

Import MCMC results:

importMCMC traces of likelihoods, parameters, biomass and recruitment
importProj medium-term projections of biomass and catch

Examples:

x.cod, x.ling, x.oreo, x.saithe, x.sbw cod, ling, oreo, and whiting assessments
xmcmc, xproj MCMC results

Note

browseVignettes() shows the vignettes, found in the ‘scape/doc’ directory.

Most scape graphics are trellis plots, rendered with the lattice package.

The functions Args and ll (package gdata) can be useful for browsing unwieldy functions and objects.

The plotMCMC package can be used to diagnose the results of MCMC analysis.
