\title{Calculate optimal cutpoints and further statistics for multiple predictors}
\usage{
multi_cutpointr(data, x = NULL, class, silent = FALSE, ...)
}
\arguments{
\item{data}{A data frame.}

\item{x}{Character vector of predictor variables. If NULL all numeric columns.}

\item{class}{The name of the outcome / independent variable.}

\item{silent}{Whether to suppress messages.}

\item{...}{Further arguments to be passed to cutpointr_ (Use a quoted variable
name for subgroup).}
}
\value{
A data frame.
}
\description{
Runs \code{cutpointr_} over multiple predictor variables. If
\code{x = NULL}, \code{cutpointr_}
will be run using all numeric columns in the data set as predictors except for the
variable in \code{class} and, if given, \code{subgroup}.
}
\details{
The automatic determination of positive / negative classes and \code{direction}
will be carried out separately for every predictor variable. That way, if
\code{direction} and the classes are not specified, the reported AUC for every
variable will be >= 0.5. AUC may be < 0.5 if subgroups are specified as
\code{direction} is equal within every subgroup.
