Standardize a vector

Description

Standardize a vector. Can use weights and robust measures of central tendency and dispersion. Returns a clean vector as opposed to base-r's scale.

Usage

standardize(x, w = NULL, robust = F, sample = T, focal_group = NULL)

Arguments

x	(num vector) A vector of values.
w	(num vector) A vector of weights.
robust	(log vector) Whether to use robust measures (default false). See mad and median.
sample	(log scalar) Whether this is a sample as opposed to a population (default true).
focal_group	(lgl vector) A subset of the data to standardize the values to. This is useful when you want one subgroup to be the focal group, using their mean/sd as 0/1.

Examples

set.seed(1)
X = rnorm(100, mean = 10, sd = 5)
set.seed(1)
W = runif(100)
standardize(X, W)
standardize(X, robust = T) #almost the same for these data
