Location of the package cache on the disk. See
\code{\link[pak:cache]{pak::cache_summary()}}. Default is selected by pkgcache.

Character vector of platforms to \emph{download} or \emph{install} packages
for. See \code{\link[pkgdepends:default_platforms]{pkgdepends::default_platforms()}} for possible platform
names. Defaults to the platform of the current R session, plus
\code{"source"}.

Character vector, R versions to download or install
packages for. It defaults to the current R version.

Whether to automatically look up and install system requirements.
If \code{TRUE}, then pkgdepends will try to install required
system packages. If \code{FALSE}, then system requirements are still
printed (including OS packages on supported platforms), but they
are not installed.
By default it is \code{TRUE} on supported platforms,
if the current user is the root user or password-less \code{sudo} is
configured for the current user.

Whether to try to update the system requirements database from
GitHub. If the update fails, then the cached or the build-in
database if used. Defaults to TRUE.

Timeout for the system requirements database update.
Defaults to five seconds, except if the \code{CI} environment variable
is set, then it is one minute.

If \code{TRUE}, then pak only prints the system commands to
install system requirements, but does not execute them.

The platform to use for system requirements lookup. On Linux, where
system requirements are currently supported, it must be a string
containing the distribution name and release, separated by a dash.
E.g.: \code{"ubuntu-22.04"}, or \code{"rhel-9"}.

Posit Package Manager (formerly RStudio Package Manager) repository
id to use for CRAN system requirements lookup. Defaults to the
\code{RSPM_REPO_ID} environment variable, if set. If not set, then it
defaults to \code{1}.

Root URL of Posit Package Manager (formerly RStudio Package
Manager) for system requirements lookup. By default the \code{RSPM_ROOT}
environment variable is used, if set. If not set,
it defaults to \verb{https://packagemanager.posit.co}.
