An ASH plot is the average over all histograms of a fixed bin width.
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")
A formula or numeric vector.
A data frame.
Additional arguments passed to panel and prepanel functions or data, a
data frame in which to find the variales used for the plot.
The historam bin width.
A numeric adjustment to width. Primarily useful when width is
not specified. Increasing adjust makes the plot smoother.
A panel funtion.
A prepanel function.
a list of arguments for the function computing the ASH.
as in other lattice plots
as in other lattice prepanel functions
One of TRUE, FALSE, "jitter", or "rug"
a logical indicating whether a reference line should be displayed
when plot.points="jitter", the value to use as the amount
argument to jitter.
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.
A character string that is prepended to the names of i grobs that are created by this panel function.
