\title{Get probabilities for some classes.}
\usage{
getPredictionProbabilities(pred, cl)
}
\arguments{
\item{pred}{[\code{\link{Prediction}}]\cr
Prediction object.}

\item{cl}{[\code{character}]\cr
Names of classes.
Default is either all classes for multi-class / multilabel problems or the positive class for binary classification.}
}
\value{
[\code{data.frame}] with numerical columns or a numerical vector if length of \code{cl} is 1.
  Order of columns is defined by \code{cl}.
}
\description{
Get probabilities for some classes.

\examples{
task = makeClassifTask(data = iris, target = "Species")

# predict probabilities
pred = predict(mod, newdata = iris)

# Get probabilities for all classes
