Cumulative Percentage Table

Description

Returns as a named vector the cumulative percentage frequency distribution of a variable x at each unique value.

Usage

cumulative.table(x)

Arguments

x

object containing data for a single variable.

Details

If x contains NA values (missing data), the cumulative percentage table will not reach 100. The table will end with the cumulative percentage of non-missing data within the object; the value remaining after subtracting this value from 100 represents the percentage of NA values within the object.

Value

A named numeric vector containing cumulative percentage frequencies, named by unique values of x and ordered numerically or alphabetically by name.
