\arguments{
\item{package}{Name of the package to install.}
\item{version}{Version of the package to install. Can either be a string giving the exact
version required, or a specification in the same format as the parenthesized expressions used
in package dependencies. One of the following formats:
\itemize{
\item An exact version required, as a string, e.g. \code{"0.1.13"}
\item A comparison operator and a version, e.g. \code{">= 0.1.12"}
\item Several criteria to satisfy, as a comma-separated string, e.g. \code{">= 1.12.0, < 1.14"}
\item Several criteria to satisfy, as elements of a character vector, e.g. \code{c(">= 1.12.0", "< 1.14")}
}}
\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.
