Plots an histogram and Gaussian fitted by Mclust

Description

Given a result of function Mclust applied to a numeric vector, this function draws the fitted Gaussian on the histogram of the data values.

Usage

  plotMix(mc, data, nbBreaks, traceDensity = TRUE,
    title = "", xlim, ylim, ...)

Arguments

Details

A shapiro test p-value is added to the plot title. This function can only deal with at the most three Gaussian.

Value

NULL

Author(s)

Anne Biton

hist, Mclust

Examples

## create a mix of two Gaussian
v <-c(rnorm(80,mean=-0.5,sd=1),rnorm(80,mean=1,sd=0.2))
## apply Mclust
mc <- Mclust(v)
## plot fitted Gaussian on histogram of v
plotMix(mc=mc,data=v,nbBreaks=30)
