\name{cast}
\alias{cast}
\title{Change the type of an array or column}
\usage{
cast(x, to, safe = TRUE, ...)
}
\arguments{
\item{x}{an \code{Array}, \code{Table}, \code{Expression}, or similar Arrow data object.}
\item{to}{\link{DataType} to cast to; for \link{Table} and \link{RecordBatch},
it should be a \link{Schema}.}
\item{safe}{logical: only allow the type conversion if no data is lost
(truncation, overflow, etc.). Default is \code{TRUE}.}
\item{...}{specific \code{CastOptions} to set}
}
\value{
An \link{Expression}
}
\description{
This is a wrapper around the \verb{$cast()} method that many Arrow objects have.
It is more convenient to call inside \code{dplyr} pipelines than the method.
}
\examples{
\dontrun{
mtcars |>
arrow_table() |>
mutate(cyl = cast(cyl, string()))
}
}
\seealso{
\code{\link{data-type}} for a list of \link{DataType} to be used with \code{to}.
