In Alessandra23/pineR: Modelling the life cycle of the pine weevil

getFirstGeneration

Description

Calculate First Generation Timings. This function calculates the timings for the first generation of a population based on initial conditions, thermal requirements, and temperature data.

Usage

getFirstGeneration(npop, t0, t1, params, stump_temp, lavalst)

Arguments

npop	A single numeric value representing the population size.
t0	A numeric vector of length 'npop' containing the initial starting day for each individual.
t1	A numeric vector of length 'npop' containing the thermal requirement (in degree days) for each individual.
params	A list containing various model parameters, such as threshold temperatures and time limits.
stump_temp	A list containing stump temperature data, including 10-day moving averages (s10).
lavalst	A numeric vector of length 'npop' initialized with zeros, to store the calculated day when each individual reaches the larval stage.

Value

A list containing:

• today: A single numeric value representing the last calculated day for the final individual in the population.

• lavalst: A numeric vector of length 'npop' containing the calculated day when each individual reaches the larval stage.
