Cumulative frequency plots

Description

A high-level function for producing a cumulative frequency plot using lattice graphics.

Usage

plotCumfreq(x, data, ...)

## S3 method for class 'formula'
plotCumfreq(x, data = NULL, subscripts, ...)

## Default S3 method:
plotCumfreq(x, ...)

prepanel.cumfreq(x, ...)

panel.cumfreq(x, type = c("smooth", "step"), groups = NULL, ...)

Arguments

x

a formula or numeric vector

data

a data frame in which x is evaluated if x is a formula.

...

other lattice arguments

subscripts

as in lattice plots

type

smooth or step-function?

groups

grouping variable

Value
