mclust3D: mclust Analysis in 3D

Description

This function conducts an mclust analysis of the data provided, and plots the points in 3D using rgl graphics. An option is provided for displaying either classical or robust confidence ellipses.

Usage

mclust3D(data, ellipse = TRUE, rob = FALSE, cl = 0.95,
	frac.pts.used = 0.8, truth = NULL,
	title = "no title provided", t.pos = NULL,
	lab.opts = FALSE, use.sym = FALSE, ...)

Value

The mclust model is returned invisibly, and a plot is produced.

Examples

require("mclust")
set.seed(666)
x <- c(rnorm(10, 3, 0.5), rnorm(10, -1, 0.5))
y <- c(rnorm(10, 1, 1), rnorm(10, -4, 0.5))
z <- c(rnorm(10, -2, 0.5), rnorm(10, 3, 0.5))
x[15] <- y[15] <- z[15] <- 4 # screw up one point
my.truth <- c(rep("Z", 10), rep("Q", 10))
mclust3D(cbind(x, y, z), title = "mclust3D demo",
	t.pos = "G", truth = my.truth)
