add_lengthgroups: Add length groups to Gadget StockStdPrinter output

In inspktrgadget/gadgetSim: Create Gadget replicates for use in simulation studies

Description

Add length groups to Gadget StockStdPrinter output

Usage

add_lengthgroups(stock_data, length_groups, variable = "number",
  keep_zero_counts = FALSE)

Arguments

stock_data	A data.frame of stock data retrieved via get_stock_std or read_gadget_stock_std
length_groups	Numeric vector of length groups to distribute by. The difference in values probably should be the same as dl in Gadget model
variable	Character vector of the variable on which to distribute length groups. Default is "number". Can be "number.consumed" or "biomass.consumed" Returns a wide data.frame similar to that of stock_data, but with values distributed across each length group which are represented as each column. The output of add_lengthgroup is meant to go directly to survey_gadget
keep_zero_counts	Logical. Keep year/step/area/age combinations with no individuals

Examples

cod_lendist <- add_lengthgroups(cod_stock_std$cod0, lengrps)
