\arguments{
|
09388373 |
\item{number_of_iterations}{(numeric, integer) The number of training sets to generate. The default is \code{10}.\cr}

|
09388373 |
\item{method}{(character) Resampling method. Allowed values are limited to the following: \itemize{ \item{\code{"split_data"}: Samples for the training set are selected at random from the full dataset.}\item{\code{"stratified_split"}: Samples for the training set are randomly selected from each level of the chosen factor.}\item{\code{"equal_split"}: Samples for the training set are selected at random from each level of the main factor such that all group sizes are equal.}} The default is \code{"split_data"}.}
|
09b8b680 |
\item{factor_name}{(character) The name of a sample-meta column to use.}
|
09388373 |
\item{p_train}{(numeric) The proportion of samples selected for the training set. The default is \code{0.8}.\cr}
|
09b8b680 |
\item{collect}{(NULL, character) The name of a model output to collect over all bootstrap repetitions, in addition to the input metric. The default is \code{NULL}.}
\item{...}{Additional slots and values passed to \code{struct_class}.}
}
\value{
A \code{resample} object with the following \code{output} slots:
\tabular{ll}{
\code{results.training} \tab (data.frame) \cr
\code{results.testing} \tab (data.frame) \cr
\code{metric} \tab (data.frame) \cr
\code{collected} \tab (list) \cr
\code{metric.train} \tab (numeric) \cr
\code{metric.test} \tab (numeric) \cr
}
}
\description{
New training sets are generated from the original data by selecting samples at random. This can be based on levels in a factor or on the whole dataset.
