Score intervals

Description

Classifies a numeric sequence of scores into a sequence of classes of scores.

Usage

score_rollup(x, x.min = NULL, x.max = NULL,
    direction = c("forward", "backward"),
    extremes = c(FALSE, FALSE))

Arguments

x	Numeric vector sorted in ascending or descending order.
x.min	Theoretical minimum of x.
x.max	Theoretical minimum of x.
direction	Specify if the classification of scores must be performed in ascending (forward) or descending (backward) order. Default is forward.
extremes	Should a value be assigned to extreme scores?. The argument can include two logical values, the first one refferring to the lower extreme, the second one referring to the upper extreme. If just one value is provided, it will be used for both extremes.

Details

Missed scores must be coded by using an empty string.
