group_prey_species: Group prey species names.

In MortenVinther/FishStomachs: Compilation of stomach contents data

Group prey species names.

Description

Prey species are renamed and re-grouped into larger groups of prey, with summed prey weights. The simplest approach maintain the species names provided by keep_prey_names and rename all other preys into "other". A more complex method uses a key based on the NODC to split (see NODC_split).

Usage

group_prey_species(
  stom,
  keep_prey_names,
  sum_other_food = TRUE,
  NODC_split,
  show_allocations = FALSE,
  verbose = FALSE
)

Arguments

stom	Stomach contents data of class STOMobs.
keep_prey_names	Names of preys to be kept unchanged. Remaining preys are renamed to "other" and their prey sizes are changed to missing.
sum_other_food	Sum stomach contents of "other" preys.
NODC_split	Input file with the fields XXXXX
show_allocations	If true the allocation of prey names into groups are shown, when the NODC_split is used. in the control object are renamed into "other".
verbose	Show extra information

Value

Stomach contents data of class STOMobs. Prey sizes and number of preys as set to missing for preys in the "other" food group.
