It is likely that you want to use create_project() or create_package() instead of use_rstudio()! Both create_*() functions can add RStudio Project infrastructure to a pre-existing project or package. use_rstudio() is mostly for internal use or for those creating a usethis-like package for their organization. It does the following in the current project, often after executing proj_set(..., force = TRUE):

  • Creates an .Rproj file

  • Adds RStudio files to .gitignore

  • Adds RStudio files to .Rbuildignore, if project is a package

use_rstudio()
