Typically we would like to use existing copies of packages in our renv cache, rather than taking time to re-download them all and rebuild them all. You can specify this option with how = "link_from_cache". Providing only the package name will install the latest available version. Providing package @1.2.3" will install package version 1.2.3. Providing package#hash will install a unique version of the package, identified by the hash. You can get the package hash list with get_cache_binary_pkg_catalog().
Alternatively we may want to install a new package or update a package from CRAN, bioconductor or another repository. Specify this with "new_or_update".
When installing local packages from tarball files, "how" is ignored, but an option for "tarball" is there for completeness. If "tarball" is selected but the package is not a tarball, a message to that effect is returned.

package,
how = c("ask", "new_or_update", "link_from_cache", "tarball")
