\arguments{
\item{dataset}{Dataset}

\item{pred}{Predictions or predictors}

\item{rvar}{Response variable}

\item{lev}{The level in the response variable defined as success}

\item{cost}{Cost for each connection (e.g., email or mailing)}

\item{margin}{Margin on each customer purchase}

\item{scale}{Scaling factor to apply to calculations}

\item{train}{Use data from training ("Training"), test ("Test"), both ("Both"), or all data ("All") to evaluate model evalbin}

\item{data_filter}{Expression entered in, e.g., Data > View to filter the dataset in Radiant. The expression should be a string (e.g., "price > 10000")}

\item{arr}{Expression to arrange (sort) the data on (e.g., "color, desc(price)")}

\item{rows}{Rows to select from the specified dataset}

\item{envir}{Environment to extract data from}

\item{...}{further arguments passed to or from other methods}
