BlightR: BlightR model.

In mladencucak/epiCrop: Set of functions and data for crop disease epidemiology work

Description

This function calculates potato late blight risk using BlightR model. The risk needs to be calculated for a single location, so if the calculation is necessary for multiple locations, data for each location needs to run separately.

Usage

BlightR(data, max_na = NULL, temporal_res = "daily",
  model_parameters = "default")

Arguments

data	The weather data formated as data frame.
max_na	Maximum proportion of missing values. Set to 0.01 by default.
temporal_res	By default, the teporal resolution of the output is daily. By changing the argument temporal_res = "hourly" user will get daily values attached at 12.
model_parameters	resoulution of the final data to be returned, daily or hourly. If hourly is selected, outputst are returned at noon.

Value

This function returns a data.frame including columns:

• date Date formated as "yyyy-mm-dd"

• spor Sporulation risk.

• spor_cond Conditions for sporulation.

• inf Infection risk.

• surv_prob Spore mortality.

• risk_si Risk as sum of infection and sporulation reduced by moratlity.

• risk_mi

• risk Risk as product of sporulation, spore survival and infection.

Examples

library(epiCrop)
weather <- system.file("data/blightR_weather.csv", package="epiCrop")
out <- system.time(BlightR(weather))
head(out)
