ashplot: Average Shifted Histograms

Description

An ASH plot is the average over all histograms of a fixed bin width.

Usage

ashplot(x, data = data, ..., width = NULL, adjust = NULL,
  panel = panel.ashplot, prepanel = prepanel.default.ashplot)
prepanel.default.ashplot(x, darg, groups = NULL, subscripts = TRUE, ...)
panel.ashplot(x, darg = list(), plot.points = FALSE, ref = FALSE,
  groups = NULL, jitter.amount = 0.01 * diff(current.panel.limits()$ylim),
  type = "p", ..., identifier = "ash")

Arguments

x

A formula or numeric vector.

data

A data frame.

...

Additional arguments passed to panel and prepanel functions or data, a data frame in which to find the variables used for the plot.

width

The histogram bin width.

adjust

A numeric adjustment to width. Primarily useful when width is not specified. Increasing adjust makes the plot smoother.

panel

A panel function.

prepanel

A prepanel function.

darg

a list of arguments for the function computing the ASH.

groups

as in other lattice plots

subscripts

as in other lattice prepanel functions

plot.points

One of TRUE, FALSE, "jitter", or "rug"

ref

a logical indicating whether a reference line should be displayed

jitter.amount

when plot.points="jitter", the value to use as the amount argument to jitter().

type

type argument used to plot points, if requested. This is not expected to be useful, it is available mostly to protect a type argument, if specified, from affecting the display of the ASH.

identifier

A character string that is prepended to the names of i grobs that are created by this panel function.

Examples

# NOT RUN {
ashplot( ~age | substance, groups = sex, data = HELPrct)
# }
