View and revert to a historical lockfile

history() uses your version control system to show prior versions of the lockfile and revert() allows you to restore one of them.

These functions are currently only implemented for projects that use git.

history(project = NULL)

revert(commit = "HEAD", ..., project = NULL)

Arguments

project: The project directory. If NULL, then the active project will be used. If no project is currently active, then the current working directory is used instead.
commit: The commit associated with a prior version of the lockfile.
...: Optional arguments; currently unused.

Value

history() returns a data.frame summarizing the commits in which renv.lock has been changed. revert() is usually called for its side-effect but also invisibly returns the commit used.

Examples

if (FALSE) { # \dontrun{

# get history of previous versions of renv.lock in VCS
db <- renv::history()

# choose an older commit
commit <- db$commit[5]

# revert to that version of the lockfile
renv::revert(commit = commit)

} # }
