\title{Subset data in task.}
\usage{
subsetTask(task, subset = NULL, features)
}
\arguments{
\item{task}{(\link{Task})\cr
The task.}
\item{subset}{(\link{integer} | \link{logical} | \code{NULL})\cr
Selected cases. Either a logical or an index vector.
By default \code{NULL} if all observations are used.}
\item{features}{(\link{character} | \link{integer} | \link{logical})\cr
Vector of selected inputs. You can either pass a character vector with the
feature names, a vector of indices, or a logical vector.\cr
In case of an index vector each element denotes the position of the feature
name returned by \link{getTaskFeatureNames}.\cr
Note that the target feature is always included in the
resulting task, you should not pass it here.
Default is to use all features.}
}
\value{
(\link{Task}). Task with subsetted data.

\description{
See title.

task = makeClassifTask(data = iris, target = "Species")
