\title{Re-run expressions multiple times}
\usage{
rerun(.n, ...)
}
\arguments{
\item{.n}{Number of times to run expressions}

\item{...}{Expressions to re-run.}
}
\value{
A list of length \code{.n}. Each element of \code{...} will be
re-run once for each \code{.n}.

There is one special case: if there's a single unnamed input, the second
level list will be dropped. In this case, \code{rerun(n, x)} behaves like
\code{replicate(n, x, simplify = FALSE)}.

This function was deprecated in purrr 1.0.0 because we believe that NSE
functions are not a  good fit for purrr. Also, \code{rerun(n, x)} can just as
easily be expressed as \verb{map(1:n, \\(i) x)}

\code{rerun()} is a convenient way of generating sample data. It works similarly to
\code{\link{replicate}(..., simplify = FALSE)}.
