Classifies new observations using parameters determined by the rda-function.
rda
# S3 method for rda predict(object, newdata, posterior = TRUE, aslist = TRUE, ...)
Object of class rda.
Data frame (or matrix) of cases to be classified.
Logical; indicates whether a matrix of posterior probabilites over all classes for each observation shall be returned in addition to classifications.
Logical; if TRUE, a list containing classifications and posterior probabilities is returned, otherwise a vector with an attribute ‘posterior’.
TRUE
posterior
currently unused
Depends on the value of argument ‘aslist’:
aslist
Either a vector (of class factor) of classifications that (optionally) has an attribute ‘posterior’ containing the posterior probability matrix, or
factor
A list with elements ‘class’ and ‘posterior’.
