Description Usage Arguments Value Note References See Also Examples

View source: R/importCol.R

Description

Import Coleraine model results from ‘.res’ file, and rearrange into a standard format suitable for plotting.

Usage

1
2
importCol(res.file, Dev=FALSE, CPUE=FALSE, Survey=FALSE, CAc=FALSE,
          CAs=FALSE, CLc=FALSE, CLs=FALSE, LA=FALSE, quiet=TRUE)

Arguments

res.file

name of Coleraine model results file to import.

Dev

whether recruitment deviates were estimated in model.

CPUE

whether model was fitted to catch-per-unit-effort data.

Survey

whether model was fitted to survey abundance index data.

CAc

whether model was fitted to commercial catch-at-age data.

CAs

whether model was fitted to survey catch-at-age data.

CLc

whether model was fitted to commercial catch-at-length data.

CLs

whether model was fitted to survey catch-at-length data.

LA

whether model was fitted to length-at-age data.

quiet

whether to report progress while parsing file.

Value

A list of class scape containing at least N, B, and Sel. The other elements may or may not be included in the list, depending on how importCol was called:

N

predicted numbers at age

B

predicted biomass, recruitment, and observed landings (year things)

Sel

predicted selectivity and observed maturity (age things)

Dev

predicted recruitment deviates from the stock-recruitment curve

CPUE, Survey

commercial and survey abundance index and fit

CAc, CAs

commercial and survey [email protected] (catch at age) and fit

CLc, CLs

commercial and survey [email protected] (catch at length) and fit

LA

observed [email protected] and fit

Note

This import function is implemented for the Coleraine statistical catch-at-age software, and can serve as a template for scape users who would like to implement import functions for specific stock assessment software.

The functions ll (package gdata) and head are recommended for browsing nested objects, e.g. ll(x.cod), ll(x.cod$N), and head(x.cod$N).
