Usage

categorize(continuous_var, nbins = 4, units = "", type = 7, digits = 1)

Arguments

continuous_var: continuous variable data
nbins: number of bins to break data into, default is 4
units: string, optional units string to add to labels of categorized data
type: type argument for stats::quantile, default is 7
digits: number of digits to round quantile breaks to for labels, default is 1

Value

a vector of categorized data as factor

Examples

x <- rnorm(1000, mean = 10, sd = 5)
categorize(x, nbins = 5)
