Examples

categorize(stats::runif(40), categ=c(0.5,0.75))
#>  [1] 1 2 2 1 3 2 1 2 2 2 1 1 1 2 1 1 2 3 1 1 2 1 2 2 1 3 3 3 3 1 1 1 1 2 1 3 1 2
#> [39] 1 1
categorize(LETTERS[1:5], categ='C')
#> [1] 1 1 2 2 2
categorize(LETTERS[1:5], categ='C',  lower=TRUE)
#> [1] 1 1 1 2 2
categorize(LETTERS[floor(5*stats::runif(20))+1], categ=LETTERS[1:5], lower=TRUE)
#>  [1] 5 2 3 2 3 1 5 3 3 2 3 2 1 3 2 1 2 3 5 2
