\arguments{
\item{dataset}{Dataset}

\item{rvar}{The response variable in the model}

\item{evar}{Explanatory variables in the model}

\item{type}{Model type (i.e., "classification" or "regression")}

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

\item{wts}{Weights to use in estimation}

\item{minsplit}{The minimum number of observations that must exist in a node in order for a split to be attempted.}

\item{minbucket}{the minimum number of observations in any terminal <leaf> node. If only one of minbucket or minsplit is specified, the code either sets minsplit to minbucket*3 or minbucket to minsplit/3, as appropriate.}

\item{cp}{Minimum proportion of root node deviance required for split (default = 0.001)}

\item{pcp}{Complexity parameter to use for pruning}

\item{nodes}{Maximum size of tree in number of nodes to return}

\item{K}{Number of folds use in cross-validation}

\item{seed}{Random seed used for cross-validation}

\item{split}{Splitting criterion to use (i.e., "gini" or "information")}

\item{prior}{Adjust the initial probability for the selected level (e.g., set to .5 in unbalanced samples)}

\item{adjprob}{Setting a prior will rescale the predicted probabilities. Set adjprob to TRUE to adjust the probabilities back to their original scale after estimation}

\item{cost}{Cost for each treatment (e.g., mailing)}

\item{margin}{Margin associated with a successful treatment (e.g., a purchase)}

\item{check}{Optional estimation parameters (e.g., "standardize")}

\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}
