plot.prod_mod function

Plotting production models

This function plots CPUE and yield values against fishing effort resulting from the production models (prod_mod ).

## S3 method for class 'prod_mod'
plot(x, display_MSY = TRUE, ...)

Arguments

• x: a object of the class "prod_mod"
• display_MSY: logical; should MSY be displayed in the graph?
• ...: optional parameters of plot function

Examples

data(trawl_fishery_Java)
output <-  prod_mod(data = trawl_fishery_Java)
plot(output, display_years = TRUE)
