avail_selection: Available as selection candidates

In AquaBPsim: Aquaculture Breeding Program Simulation

Available as selection candidates

Description

Function to determine which fish are available for selection. Fish are randomly chosen.

Usage

avail_selection(gen, batch = 0, presel = 0, surv = NA, fish_per_FSfam = NA)

Arguments

gen	The generation of the fish.
batch	The batch of the fish. Default is 0. It is possible to provide a vector with multiple batches.
presel	Identifies which preselected fish are available for selection. If no pre-selection took place, then presel should be 0 (= default).
surv	Proportion of fish that is assumed to survive till the moment of selection. Either surv or fish_per_FSfam need to be provided.
fish_per_FSfam	The number of fish available for selection per full sib family. Fish are randomly selected within a full sib family if fish_per_FSfam is specified. Either surv or fish_per_FSfam need to be provided.

Value

This function will make changes to the data frame called 'ped'. Fish that become available as selection candidates will be assigned a 1 to their column 'selcand'.
