Use approx() to Return a Modifier Value From an RcA or RcT Curve

Usage

.fn_Rc(.Rc, .xout)

Arguments

.Rc

A matrix describing a growth curve for either temperature, RcT, age, RcA, or relative humidity, RcRH.

.xout

a value for x, either a temperature, age or relative humidity modifier value.

Value

A numeric value for modifying a growth curve in seir.

Note

This is a faster (and more simple) function that does what the original cropsim afgen() does.

The original implementation of this function comes from ZeBook and was adapted for use in epicrop by Adam H. Sparks.
