spain: Spain TPM

In ggcostoya/limon: Evolutionary Constraints among Thermal Performance Traits

Description

Predicts performance (p) at a given temperature (t) using a Spain thermal-performance model (TPM).

Usage

spain(t, s, a, b, c)

Arguments

t	A temperature value or vector
s	Scaling parameter
a	Parameter determining the steepness of the rising portion of the curve.
b	Parameter determining the position of the maximum of the curve (Topt).
c	Parameter determining the steepness of the decreasing part of the curve.

Value

A value or vector of predicted performance values
