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

by default.

z(x)

x | A numeric vector. |
---|

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

.

x <- rnorm(500, mean = 10, sd = 5) z_vals <- z(x) round(c(mean = mean(z_vals), sd = sd(z_vals)), 2)#> mean sd #> 0 1
