In hyperSpec: Work with Hyperspectral Data, i.e. Spectra + Meta Information (Spatial, Time, Concentration, ...)

Description

Normalize numbers -> [0, 1]

Usage

normalize01(x, ...)

## S4 method for signature 'matrix'
normalize01(x, tolerance = hy.getOption("tolerance"))

## S4 method for signature 'numeric'
normalize01(x, tolerance = hy.getOption("tolerance"))

## S4 method for signature 'hyperSpec'
normalize01(x, ...)

Arguments

x	vector with values to transform
...	additional parameters such as tolerance handed down.
tolerance	tolerance level for determining what is 0 and 1

Details

The input x is mapped to [0, 1] by subtracting the minimum and subsequently dividing by the maximum. If all elements of x are equal, 1 is returned.

Value

vector with x values mapped to the interval [0, 1]
