Welcome to renv! It looks like this is your first time using renv.
This is a one-time message, briefly describing some of renv's functionality.
This package maintains a local cache of data on the filesystem at:
- '~/.local/share/renv'
This path can be customized -- see the documentation in `?paths`.
renv will also write to files within the active project folder, including:
- A folder 'renv' in the project directory, and
- A lockfile called 'renv.lock' in the project directory.
In particular, projects using renv will normally use a private, per-project
R library, in which new packages will be installed. This project library is
isolated from other R libraries on your system.
In addition, renv will attempt to update files within your project, including:
- .gitignore
- .Rbuildignore
- .Rprofile
Please read the introduction vignette with `vignette("renv")` for more information.
You can also browse the package documentation online at http://rstudio.github.io/renv.
By providing consent, you will allow renv to write and update these files.
