Description

Given a result of function Mclust applied on several numeric vectors, this function plots the fitted Gaussian on their histograms.

Usage

1
2
  plotAllMix(mc, A, nbMix = NULL, pdf, nbBreaks = 20,
    xlim = NULL)

Arguments

mc

A list consisting of outputs of function Mclust applied to each column of A, if this argument is missing Mclust is applied by the function.

A

A data.frame of dimensions 'samples x components'.

nbMix

The number of Gaussian to be fitted.

nbBreaks

The number of breaks for the histogram.

xlim

x-axis limits to be used in the plot.

pdf

A pdf file.

Details

This function can only deal with at the most three Gaussian

Value

A list of Mclust results.

A <-matrix(c(c(rnorm(80,mean=-0.5,sd=1),rnorm(80,mean=1,sd=0.2)),rnorm(160,mean=0.5,sd=1),
           c(rnorm(80,mean=-1,sd=0.3),rnorm(80,mean=0,sd=0.2))),ncol=3)
## apply function Mclust to each column of A
mc <- apply(A,2,Mclust)
## plot the corresponding Gaussians on the histogram of each column
plotAllMix(mc=mc,A=A)
## apply function Mclust to each column of A, and impose the fit of two Gaussian (G=2)
mc <- apply(A,2,Mclust,G=2)
## plot the corresponding Gaussians on the histogram of each column
plotAllMix(mc=mc,A=A)
## When arg 'mc' is missing, Mclust is applied by the function
plotAllMix(A=A)
