Set the recommended illuminance/MEDI levels by Brown et al. (2022)

Description

This is a lower level function. It sets the recommended illuminance/MEDI levels by Brown et al. (2022) for a given state. The function is vectorized.

Usage

Brown_rec(
  state,
  Brown.day = "day",
  Brown.evening = "evening",
  Brown.night = "night",
  Brown.day.th = 250,
  Brown.evening.th = 10,
  Brown.night.th = 1
)

Arguments

state	The state from Brown et al. (2022). Needs to be a character vector.
Brown.day, Brown.evening, Brown.night	The names of the states from Brown et al. (2022). These are the default values ("day", "evening", "night"), but can be changed if the names in state are different. Needs to be a character scalar.
Brown.day.th, Brown.evening.th, Brown.night.th	The thresholds for the states from Brown et al. (2022). These are the default values (250, 10, 1), but can be changed if the thresholds should be different. Needs to be a numeric scalar.

Value

A dataframe with the same length as state that contains the recommended illuminance/MEDI levels.
