\title{Install specified version of a CRAN package.}
\usage{
install_version(package, version = NULL, repos = getOption("repos"),
type = getOption("pkgType"), ..., quiet = FALSE)
}
\arguments{
\item{package}{package name}
\item{version}{If the specified version is NULL or the same as the most
recent version of the package, this function simply calls
\code{\link{install}}. Otherwise, it looks at the list of
archived source tarballs and tries to install an older version instead.}
\item{repos}{
character vector, the base URL(s) of the repositories
to use, e.g., the URL of a CRAN mirror such as
\code{"https://cloud.r-project.org"}. For more details on
supported URL schemes see \code{\link{url}}.
Can be \code{NULL} to install from local files, directories or URLs:
this will be inferred by extension from \code{pkgs} if of length one.
}
\item{type}{character, indicating the type of package to download and
install. Will be \code{"source"} except on Windows and some macOS
builds: see the section on \sQuote{Binary packages} for those.
}
\item{...}{Other arguments passed on to \code{\link{install}}.}
\item{quiet}{
logical: if true, reduce the amount of output.
}
}
\description{
If you are installing an package that contains compiled code, you will
need to have an R development environment installed. You can check
if you do by running \code{\link[pkgbuild]{has_build_tools}}.
