Example Performance Metric: Calculate the coefficient of variation of catch

Source: R/example_perf_metrics.R
get_catch_cv.Rd

Example performance metric that calculates the coefficient of variation (CV) of catch over a range of years in a Stock Synthesis data file. This function aggregates across fleets, so may not be appropriate for models with multiple fleets.

Usage

get_catch_cv(datfile, yrs)

Arguments

datfile

Path to the Stock Synthesis data file containing catch

yrs

A vector containing a range of years. Years are as defined in the Stock Synthesis data file.

Value

The catch coefficient of variation, a number.

Examples

if (FALSE) { # \dontrun{
catch_cv <- get_catch_cv(datfile = "mod/dat.ss", yrs = c(20:50, 75:100))
catch_cv
} # }
