nWorkersFun: Sample a number of workers

In SIMplyBee: 'AlphaSimR' Extension for Simulating Honeybee Populations and Breeding Programmes

Sample a number of workers

Description

Sample a number of workers - used when nInd = NULL (see SimParamBee$nWorkers).

This is just an example. You can provide your own functions that satisfy your needs!

Usage

nWorkersPoisson(colony, n = 1, average = 100)

nWorkersTruncPoisson(colony, n = 1, average = 100, lowerLimit = 0)

nWorkersColonyPhenotype(
  colony,
  queenTrait = 1,
  workersTrait = NULL,
  checkProduction = FALSE,
  lowerLimit = 0,
  simParamBee = NULL,
  ...
)

Arguments

colony	Colony-class
n	integer, number of samples
average	numeric, average number of workers
lowerLimit	numeric, returned numbers will be above this value
queenTrait	numeric (column position) or character (column name), trait that represents queen's effect on the colony phenotype (defined in SimParamBee - see examples); if 0 then this effect is 0
workersTrait	numeric (column position) or character (column name), trait that represents workers's effect on the colony phenotype (defined in SimParamBee - see examples); if 0 then this effect is 0
checkProduction	logical, does the phenotype depend on the production status of colony; if yes and production is not TRUE, the result is above lowerLimit
simParamBee	SimParamBee, global simulation parameters
...	other arguments of mapCasteToColonyPheno

Details

nWorkersPoisson samples from a Poisson distribution with a given average, which can return a value 0. nDronesTruncPoisson samples from a zero truncated Poisson distribution.

nWorkersColonyPhenotype returns a number (above lowerLimit) as a function of colony phenotype, say queen's fecundity. Colony phenotype is provided by mapCasteToColonyPheno. You need to set up traits influencing the colony phenotype and their parameters (mean and variances) via SimParamBee (see examples).

Value

numeric, number of workers

Functions

• nWorkersTruncPoisson(): Sample a non-zero number of workers

• nWorkersColonyPhenotype(): Sample a non-zero number of workers based on colony phenotype, say queen's fecundity
