\title{Number of unique values for pre-processing}
\usage{
min_unique(range = c(5L, 15L), trans = NULL)
}
\arguments{
\item{range}{A two-element vector holding the \emph{defaults} for the smallest and
largest possible values, respectively. If a transformation is specified,
these values should be in the \emph{transformed units}.}

\item{trans}{A \code{trans} object from the \code{scales} package, such as
\code{scales::transform_log10()} or \code{scales::transform_reciprocal()}. If not provided,
the default is used which matches the units used in \code{range}. If no
transformation, \code{NULL}.}
}
\description{
Some pre-processing parameters require a minimum number of unique data points
to proceed. Used in \code{recipes::step_discretize()}.
