hist.CAMAN.object: Histograms for finite mixture models

Description

Graphical display of the data and the mixture. Intended for larger data sets.

Usage

# S3 method for CAMAN.object
hist(x, nbreaks=NULL, mixdens=TRUE, mixdens.col="red", 
                return.mixdens=FALSE, data.plot=NULL, singleDistr=TRUE, 
                main="", xlab="", plotlegend=TRUE, ...)

Value

The function plots a histogram with the mixture density and its components overlaid. If return.mixdens is set to TRUE, the density at the breaks will also be returned.

Arguments

x

A CAMAN.object.

nbreaks

Number of breaks in histogram. Defaults to NULL. In this case it is set to min(60,max(30,x@num.obs)). Passed on to hist.

mixdens

logical; plot mixture density?

mixdens.col

color of mixture density.

return.mixdens

logical; return the mixture density?

data.plot

data to plot. Defaults to NULL. In this case it is taken from the data of the mixture density.

singleDistr

logical; should the distributions of the single components be plotted?

main

character; heading of the plot.

xlab

character; label of x-axis.

plotlegend

logical; should a legend be plotted.

...

arguments to be passed on to hist.
