Arguments

histValues

an object of class histogram. See hist.

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.

Examples

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

  z <- round(rnorm(100, 30, 5))
  h <- hist(z, plot = FALSE)

  l <- c(10, 20, 30, 40)
  xyplot(1:50 ~ 1:50, histValues = h, densi = d, drawLines = l,
