Package 'mountainplot'

Mountainplot

Description

A mountain plot is similar to an empirical CDF, but _decreases_ from .5 down to 1, using a separate scale on the right axis.

Usage

mountainplot(x, data, ...)

mountainplotyscale.components(...)

## S3 method for class 'formula'
mountainplot(
  x,
  data = NULL,
  prepanel = "prepanel.mountainplot",
  panel = "panel.mountainplot",
  ylab = gettext("Folded Empirical CDF"),
  yscale.components = mountainplotyscale.components,
  scales = list(y = list(alternating = 3)),
  ...
)

## S3 method for class 'numeric'
mountainplot(x, data = NULL, xlab = deparse(substitute(x)), ...)

Arguments

x	Variable in the data.frame 'data'.
data	A data frame
...	Other arguments
prepanel	The prepanel function. Default "prepanel.mountainplot".
panel	The panel function. Default "panel.mountainplot".
ylab	Vertical axis label.
yscale.components	Function for drawing left and right side axes.
scales	The "scales" argument used by lattice functions.
xlab	Horizontal axis label.

Details

Note that 'mountainplotyscale.components' is not really intended to be called by the user, but is used by lattice to configure the right-axis ticks and labels.

Value

A lattice object
