Heat Index
Combines air temperature and relative humidity to determine the human-perceived equivalent temperature
hi(taverage, rh, data_names = NULL, time.scale = YEAR, na.rm = FALSE)
taverage |
daily mean temperature, Celsius |
rh |
relative humidity, percentage |
data_names |
names of each period of time |
time.scale |
month, season or year |
na.rm |
logical. Should missing values (including NaN) be removed? |
