The function determines which packages in a repositories can be removed as they are being ‘shadowed’ by a newer version of the same packages.
pruneRepo(repopath = getOption("dratRepo", "~/git/drat"),
type = "source", pkg, remove = FALSE)
Character variable with the path to the repo; defaults to the value of the “dratRepo” option with “"~/git/drat"” as fallback
Character variable for the type of repository, so far “source”
Optional character variable specifying a package name, whose older versions should be pruned. If missing (the default), pruning is performed on all packages.
Character or logical variable indicating whether
files should be removed. Nothing happens if ‘FALSE’. If
different from (logical) ‘FALSE’ and equal to character
“git” files are removed via git rm
else via a
straight file deletion.
A data frame describing the repository is returned containing columns with columns “file”, “package” (just the name), “version” and a logical variable “newest” indicating if the package can be removed.
Given a package name, R will always find the newest version of that package. Older versions are therefore effectively shadowed and can be removed without functionally changing a repository.
This function is still undergoing development and polish and may change in subsequent versions.
