Holdridge points

Description

Calculates the values of bioclimatic indices from monthly temperature and precipitation measurements, following Szelepcsényi et al. 2014.

Usage

bioclimate(temp, prec)

Arguments

temp	A matrix or data frame with 12 columns containing temperatures, in degrees C, for each month of the calendar year.
prec	A matrix or data frame with the same dimensions as temp, containing precipitation measurements in mm for each month of the year.

Value

bioclimate() returns a data.frame whose columns correspond to:

• abt, mean annual biotemperature; mean annual temperature after replacing entries outside the range 0° to 30° with zeros;

• tap, total annual precipitation (mm);

• per, potential evapotranspiration ratio
