This function provides an API for creating and modifying renv lockfiles. This can be useful when you'd like to programmatically generate or modify a lockfile -- for example, because you want to update or change a package record in an existing lockfile.

lockfile(file = NULL, project = NULL)

Arguments

file

The path to an existing lockfile. When no lockfile is provided, a new one will be created based on the current project context. If you want to create a blank lockfile, use file = NA instead.

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.

Examples

if (FALSE) { lock <- lockfile("renv.lock") # set the repositories for a lockfile lock$repos(CRAN = "https://cran.r-project.org") # depend on digest 0.6.22 lock$add(digest = "digest@0.6.22") # write to file lock$write("renv.lock") }
