\title{Get the class weight parameter of a learner.}
\usage{
getClassWeightParam(learner, lrn.id = NULL)
}
\arguments{
\item{learner}{(\link{Learner} | \code{character(1)})\cr
The learner.
If you pass a string the learner will be created via \link{makeLearner}.}

\item{lrn.id}{(\link{character})\cr
Only used for \code{BaseEnsembles}. It is possible that multiple learners in a base
ensemble have a class weight param. Specify the learner from which the class weight should
be extracted.}
}
\value{
\link{numeric} \link{LearnerParam}:
A numeric parameter object, containing the class weight parameter of the given learner.
}
