Panel function for adding histograms.

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.

Examples

if(require(KernSmooth, quietly = TRUE) & require(lattice, quietly = TRUE)) {

  z <- round(rnorm(100, 30, 5))
  h <- hist(z, plot = FALSE)
  d <- bkde(z, kernel = "normal", gridsize = 60)
  l <- c(10, 20, 30, 40)
  xyplot(1:50 ~ 1:50, histValues = h, densi = d, drawLines = l, 
    panel = function(drawLines, histValues, densi){
      adeg.panel.hist(histValues = histValues, drawLines = drawLines, densi = densi)})
}
