archive.packages(repo.root, to.dir = "Archive", keep = 1, package = NULL,
  type = "source", archive.root = repo.root, overwrite = FALSE,
  reallyDoIt = FALSE)

`repo.root`	Path to the repository root, i.e., the directory which contains the `src` and `bin` directories. Usually this path should start with "`file:///`" except for Windows.
`to.dir`	Character string, name of the folder to move the old packages to.
`keep`	An integer value defining the maximum nuber of versions to keep. Setting this to 0 will completely remove all packages from the repository, which is probably only useful in combination with the option `package`.
`package`	A character vector with package names to check. If set, `archive.packages` will only take actions on these packages. If `NULL`, all packages are affected.
`type`	A character vector defining the package formats to keep. Valid entries are `"source"`, `"win.binary"` and `"mac.binary.leopard"`. By default, only the source packages are archived, all other packages are deleted.
`archive.root`	Path to the archive root, i.e., the directory to which files should be moved. Usually the Archive is kept i `repo.root`
`overwrite`	Logical, indicated whether existing files in the archive can be overwritten.
`reallyDoIt`	Logical, real actions are only taken if set to `TRUE`, otherwise the actions are only printed.

This function responds to sandbox.

sandbox to run archive.packages() in a sandbox.

## Not run: 
# dry run, only prints what would happen, so you can check
# if that's really what you want
archive.packages("file:///var/www/repo")

# after we've confirmed that the right packages will be moved
# and deleted, let's actually commit the changes
archive.packages("file:///var/www/repo", reallyDoIt=TRUE)

# if we don't want a standard archive, but for instance a parallel
# archive repository, we can have it. let's move all but the latest two
# versions from /var/www/repo to /var/www/archive. to suppress the
# creation of a special archive directory, we set to.dir=""
archive.packages("file:///var/www/repo", to.dir="", keep=2,
  type=c("source", "win.binary", "mac.binary.leopard"),
  archive.root="/var/www/archive", reallyDoIt=TRUE)
