extract.mixturepars: Extract parameters for certain components from mclust

Description

Extracts parameters of certain mixture components from the output of summary.mclustBIC and updates proportions so that they sum up to 1.

Usage

extract.mixturepars(mclustsum,compnumbers,noise=FALSE)

Arguments

mclustsum

output object of summary.mclustBIC.

compnumbers

vector of integers. Numbers of mixture components.

noise

logical. Should be TRUE if a noise component was fitted by mclustBIC.

Value

Object as component parameters of summary.mclustBIC-output, but for specified components only. (Orientation information from all components is kept.)

Examples

# NOT RUN {
  set.seed(98765)
  require(mclust)
  iriss <- iris[sample(150,20),-5]
  irisBIC <- mclustBIC(iriss,G=5,modelNames="VEV")
  siris <- summary(irisBIC,iriss)
  emp <- extract.mixturepars(siris,2)
  emp$pro
  round(emp$mean,digits=1)
  emp$variance$modelName
  round(emp$variance$scale,digits=2)
