calculate_db: Calculate accuracy of temperature regulation

In ectotemp: Quantitative Estimates of Small Ectotherm Temperature Regulation Effectiveness

Description

This function determines the degree to which ectotherms experience body temperatures outside their set-point range, better known as the accuracy of temperature regulation (db) as described by Hertz et al. (1993). Descriptive statistics are automatically computed as well.

Usage

calculate_db(tb, tset_low, tset_up)

Arguments

tb	A vector containing body temperature measurements.
tset_low	Lower boundary of a species or population set-point range that was determined through thermal preference trials in a temperature gradient.
tset_up	Upper boundary of the set-point range.

Value

Degree to which ectotherms experience body temperatures outside their set-point range (db), and associated descriptive statistics.
