standardize: Custom Function to Standardize a Variable

In rettopnivek/utilityf: Useful Functions for Modeling and Plotting

Description

This function centers and scales a variable, and adds attributes that allow the function to convert the standardized variable back into its original scale.

Usage

standardize(x, reverse = F)

Arguments

x	a numerical value.
reverse	logical; if true, the function extracts the 'mean' and 'scale' attributes and reverses the standardization.

Value

If reverse is FALSE, returns the standardized values for x, with attributes giving the mean and scale; otherwise, returns the raw, unstandardized values of x.

Examples

x = runif( 30 )
# Standardize the variable
z = my_standardize( x )
# Unstandardize the variable
y = my_standardize( x, reverse = T )
all( x == y )
