classify specimen based on between-group PCA or CVA or typprobClass

Description

classify specimen based on between-group PCA, CVA or typprobClass

Usage

classify(x, cv = TRUE, ...)

## S3 method for class 'bgPCA'
classify(x, cv = TRUE, newdata = NULL, ...)

## S3 method for class 'CVA'
classify(x, cv = T, newdata = NULL, prior = NULL, ...)

## S3 method for class 'typprob'
classify(x, cv = TRUE, ...)

Arguments

x	result of groupPCA, CVA or typprobClass
cv	logical: use cross-validated scores if available
...	currently not used
newdata	use new data to predict scores and evaluate group affinity
prior	specify prior probability for CVA evaluation if NULL prior from CVA will be used. Be m your number of groups then to set the prior equally for all groups set prior=rep(1,m)/m.

Value

class	classification result
groups	original grouping variable, only available if newdata=NULL
posterior	only for object of CVA and typprob, also the posterior probabilities are returned
