In tadaatoolbox: Helpers for Data Analysis and Presentation Focused on Undergrad Psychology

Description

A trivial scaling function. You might as well use base::scale, which allows arbitrary centers and scales, but returns a matrix by default.

Usage

z(x)

Arguments

x	A numeric vector.

Value

A vector of z-values of the same length as x.

Examples

x <- rnorm(500, mean = 10, sd = 5)
z_vals <- z(x)
round(c(mean = mean(z_vals), sd = sd(z_vals)), 2)

Example output

mean   sd 
   0    1
