| 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’.
