R: Scale a vector

n_scaled

R Documentation

Scale a vector

Description

Scales a vector for normalisation using the method applied in the GII2020 for some indicators. This does x_scaled <- (x-l)/(u-l) * 100. Note this is not the minmax transformation (see n_minmax()). This is a linear transformation with shift u and scaling factor u-l.

Usage

n_scaled(x, npara = c(0, 100))

Arguments

`x`	A numeric vector
`npara`	Parameters as a vector `c(l, u)`. See description.

Value

Scaled vector

Examples

x <- runif(20)
n_scaled(x, npara = c(1,10))
