cum_dev_rate: Cumulative Development Rates

In phenModel: Insect Phenology Model Evaluation Based on Daily Temperatures

Description

Returns the cumulative development rates calculated when the phenology model is being evaluated.

Usage

cum_dev_rate(Tmean, thermal_units, chill_days, day_length,
             bud_pars, weib_pars, lactin_pars, max_day_length,
             pop_quantiles = 0.5, data)

Arguments

Tmean	name of the column in the data representing the mean temperature
thermal_units	name of the column in the data representing the thermal units
chill_days	name of the column in the data representing the number of chill days
day_length	name of the column in the data representing the day length
bud_pars	vector of parameters for the budburst model
weib_pars	matrix of parameters for the Weibull model for each developmental stage
lactin_pars	matrix of parameters for the lactin model for each developmental stage
max_day_length	critical day length threshold
pop_quantiles	quantile of the population to be evaluated by the phenology model
data	a data.frame

Value

Returns the data with an appended column representing the cumulative development rates evaluated by the model.
