Hydrate a ProjectSource:
Discover the R packages used within a project, and then install those packages into the active library. This effectively allows you to fork the state of your default R libraries for use within a project library.
hydrate( packages = NULL, ..., library = NULL, update = FALSE, sources = NULL, project = NULL )
The set of R packages to install. When
NULL, the set of packages as reported by
Unused arguments, reserved for future expansion. If any arguments are matched to
renvwill signal an error.
The R library to be hydrated. When
NULL, the active library as reported by
hydrate()attempt to update already-installed packages if the requested package is already installed in the project library? Set this to
"all"if you'd like all packages to be refreshed from the source library if possible.
A set of library paths from which
renvshould attempt to draw packages. See Sources for more details.
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.
A named R list, giving the packages that were used for hydration as well as the set of packages which were not found.
It may occasionally be useful to use
renv::hydrate() to update the packages
used within a project that has already been initialized. However, be warned
that it's possible that the packages pulled in may not actually be compatible
with the packages installed in the project library, so you should exercise
caution when doing so.
hydrate() attempts to re-use packages already installed on your system,
to avoid unnecessary attempts to download and install packages from remote
NULL (the default),
hydrate() will attempt to discover R
packages from the following sources (in order):
The user library,
The site library,
The system library,
If package is discovered in one of these locations,
renv will attempt to
copy or link that package into the requested library as appropriate.
renv discovers that your project depends on R packages not currently
installed in your user library, then it will attempt to install those
packages from the active R repositories.
