Create gear and fleet groups

create_groups(
  data,
  gear_groups,
  gear_names,
  fleet_colname,
  fleet_groups,
  fleet_names
)

Arguments

data: A data frame of WCGOP catch data that includes all species.
gear_groups: List object of gear names to group together based on the WCGOP gear column, example: list(c("Bottom Trawl", "Midwater Trawl"), c("Hook & Line", "Pot", "Fixed Gear")).
gear_names: Vector of gear group names that needs to match the length of the gear_groups object and align in order of the assigned names. For example, if gear_groups = list(c("Bottom Trawl", "Midwater Trawl"), c("Hook & Line", "Pot", "Fixed Gear")) then gear_names = c("trawl", "fixed gear")).
fleet_colname: Column in the biological data that should be used to define the fleet areas. Commonly used columns is r_state which can allow you to group or split data by state. The area column can be used to split data north and south of 4010 N. lat.
fleet_groups: List object of how to combine the data to define fleet groups. For example, list(c("WA", "OR"), "CA") would define WA-OR and CA fleets.
fleet_names: Vector of fleet names that needs to match the length of the fleet_groups object and align in order of the assigned names. For example, the fleet_names should be c("OR-WA", "CA") to align with a fleet_groups of list(c("WA", "OR"), "CA").
