predict PPtree

Description

predict projection pursuit classification tree

Usage

PPclassify_MOD(Tree.result,test.data,true.class=NULL,...)

Arguments

Tree.result	PPtreeclass object
test.data	the test dataset
true.class	true class of test dataset if available
...	arguments to be passed to methods

Details

Examples

data(iris)
n <- nrow(iris)
tot <- c(1:n)
n.train <- round(n*0.9)
set.seed(12999)
train <- sample(tot,n.train)
test <- tot[-train]
Tree.result <- PPTreeclass_MOD(formula = Species~.,data = iris[train,],PPmethod = "LDA")
PPclassify_MOD(Tree.result,test.data = iris[test,1:4], true.class = iris[test,5])
