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