Description

Quantifies the chill accumulation by means of converting temperatures to exponential units temperature.

Usage

Arguments

x

Vector containing temperature values (Celsius-degree).

total

TRUE Shows the total value of accumulation, FALSE shows the value of chill for each temperature (TRUE is default).
