standardize: Standardize numeric variables

In Rkabacoff/factorAnalysis: Principal Components, Factor Analysis, and Clustering Tools

Standardize numeric variables

Description

Standardize the numeric variables in a data frame

Usage

standardize(data, mean = 0, sd = 1, include_dummy = FALSE)

Arguments

data	a data frame.
mean	mean of the transformed variables.
sd	standard deviation of the transformed variables.
include_dummy	logical. If TRUE, transform dummy coded (0,1) variables.

Details

standardize transforms all the numeric variables in a data frame to have the same mean and standard deviation. By default, this will be a mean of 0 and standard deviation of 1. Character variables and factors are left unchanged. By default, dummy coded variables are also left unchanged. Use include_dummy=TRUE to transform these variables as well.

Value

a data frame

Examples

head(mtcars)

mtcars_st <- standardize(mtcars)
head(mtcars_st)
