adeg.panel.hist {adegraphics}R Documentation

Panel function for adding histograms.

Description

Panel function for displaying histograms into a trellis graphic (lattice package) and level lines.

Usage

adeg.panel.hist(histValues, horizontal = TRUE, densi, drawLines, params = list(), 
  identifier = "histogramADEg")

Arguments

histValues

an object of class histogram. See hist.

horizontal

a logical indicating if the plot is horizontal

densi

a list returns by the bkde containing the coordinates of the binned kernel density estimate of the probability density of the data

drawLines

a vector containing the level values

params

graphical parameters : plot.polygon, add.line and plot.line (lattice)

identifier

A character string that is prepended to the name of the grob that is created.

Value

Displays the histogram and level lines.

Note
