adjust: A generic function to scale the values of a vector between -1...

In InfDim: Infine-dimensional model (IDM) to analyse phenotypic variation in growth trajectories.

Description

A generic function to scale the values of a vector between -1 and 1. The function is used in the IDM calculation, to scale a vector of ages at which size has been measured.

Usage

adjust(age)

Arguments

age	A numeric vector containing ages to be scaled between -1 and 1.
