warnRelatives: Warning Relatives When Under Attack

In homerhanumat/simaltruist: Altruistic Behavior in Animal Populations

Description

Default function to govern behavior of warners under attack. Warner warns a specified number of the most closely-related individuals. May be used as an alternative function in which the values of warnable_relationship and dominant are specified.

Usage

warnRelatives(individuals, number_warned, warner_death_prob,
  nonwarner_death_prob, hider_death_prob, warnable_relationship, relMatrix,
  dominant = FALSE)

Arguments

individuals	Data frame containing id, sex, warner-status, mother id and father id. Value provided.
number_warned	Maximum number of individuals to warn. Value provided.
warner_death_prob	As in simulate. Value provided.
nonwarner_death_prob	As in simulate. Value provided.
hider_death_prob	As in simulate. Value provided.
warnable_relationship	Lowest allowed relationship-degree for an individual to be eligible for warning. Default version sets this to 0.25.
relMatrix	The current relationship matrix. Value provided.
dominant	If TRUE, individuals with 1 or more altruistic alleles can warn. Default version sets this to FALSE.

Value

A numerical vector of death probabilities in which the i^{\text{th}} element corresponds to row i of individuals.

                    number_warned = 7,
                    warnable_relationship = 0.1,
                    dominant = TRUE)))
