adeg.panel.hist {adegraphics}

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

For more information about the use of panel functions, please see the lattice package developed by Deepayan Sarkar.
