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(line_ending = c("posix", "windows"), reformat = TRUE)Line ending
If TRUE, the .Rproj is setup with common options that
reformat files on save: adding a trailing newline, trimming trailing
whitespace, and setting the line-ending. This is best practice for
new projects.
If FALSE, these options are left unset, which is more appropriate when
you're contributing to someone else's project that does not have its own
.Rproj file.
