normVec: Normalize a Vector to range -1 to +1

Description

Each value of the vector passed to the function is divided by the square root of the sum of every value squared, producing a new vector whose range is restricted to, at most, -1 to +1. Note that this assumes that the mean of the original vector is zero.

Usage

normVec(x)

Arguments

x

A numeric argument whose values are to be normalized.

Value

• The normalized vector.

Examples

x1 <- rnorm(20, 2, 2)
range(x1)
sd(x1)/diff(range(x1))
x2 <- normVec(x1)
range(x2)
sd(x2)/diff(range(x2))
