\title{Convert large/infinite numeric values in a data.frame or task.}
\usage{
capLargeValues(obj, target = character(0L), cols = NULL, threshold = Inf,
  impute = threshold, what = "abs")
}
\arguments{
\item{obj}{[\code{data.frame} | \code{\link{Task}}]\cr
Input data.}

\item{target}{[\code{character}]\cr
Name of the column(s) specifying the response.
Target columns will not be capped.
Default is \code{character(0)}.}

\item{cols}{[\code{character}]\cr
Which columns to convert.
Default is all numeric columns.}

\item{threshold}{[\code{numeric(1)}]\cr
Threshold for capping.
Every entry whose absolute value is equal or larger is converted.
Default is \code{Inf}.}

\item{impute}{[\code{numeric(1)}]\cr
Replacement value for large entries.
Large negative entries are converted to \code{-impute}.
Default is \code{threshold}.}

\item{what}{[\code{character(1)}]\cr
What kind of entries are affected?
\dQuote{abs} means \code{abs(x) > threshold},
\dQuote{pos} means \code{abs(x) > threshold && x > 0},
\dQuote{neg} means \code{abs(x) > threshold && x < 0}.
Default is \dQuote{abs}.}
}
\value{
[\code{data.frame}]
}
\description{
Convert numeric entries which large/infinite (absolute) values
in a data.frame or task.
Only numeric/integer columns are affected.
}
