plot.histde: Plot for histogram density estimate

In ks: Kernel Smoothing

Plot for histogram density estimate

Description

Plot for histogram density estimate for 1- and 2-dimensional data.

Usage

## S3 method for class 'histde'
plot(x, ...)

Arguments

x

object of class histde (output from histde)

...

other graphics parameters: col plotting colour for density estimate col.fun plotting colour function for levels col.pt plotting colour for data points jitter flag to jitter rug plot (1-d). Default is TRUE. xlim,ylim axes limits xlab,ylab axes labels add flag to add to current plot. Default is FALSE. drawpoints flag to draw data points on density estimate. Default is FALSE. breaks vector of break values of density estimate. Default is an nbreaks equilinear sequence over the data range. nbreaks number of breaks in breaks sequence lty.rect,lwd.rect line type/width for histogram box lines (2-d) border colour of histogram box lines (2-d) col.rect colour of histogram bars (1-d) add.grid flag to add histogram grid (2-d). Default is TRUE.

Details

For histde objects, the function headers for the different dimensional data are

  ## univariate
  plot(fhat, xlab, ylab="Density function", add=FALSE, drawpoints=FALSE,
     col.pt=4, jitter=FALSE, border=1, alpha=1, ...) 
  
  ## bivariate
  plot(fhat, breaks, nbreaks=11, xlab, ylab, zlab="Density function", cex=1, 
     pch=1, add=FALSE, drawpoints=FALSE, col, col.fun, alpha=1, col.pt=4,
     lty.rect=2, cex.text=1, border, lwd.rect=1, col.rect="transparent",
     add.grid=TRUE, ...)

The 1-d plot is a standard plot of a histogram generated by hist. If drawpoints=TRUE then a rug plot is added.

The 2-d plot is similar to the display="filled.contour" option from plot.kde with the default nbreaks=11 contour levels.

Value

Plots for 1-d and 2-d are sent to graphics window.

Examples

## univariate example
data(iris)
fhat <- histde(x=iris[,2])
plot(fhat, xlab="Sepal length")

## bivariate example
fhat <- histde(x=iris[,2:3])
plot(fhat, drawpoints=TRUE)
box()
