Add "Create .lintr" command

[eitsupi]

How about adding a command to add a .lintr file to the workspace, similar to the command that already exists to add .gitignore?
(Perhaps a function in the {lintr} or {languageserver} package would be more appropriate ?)

When I used vscode-R and R LSP for the first time, I struggled a lot because I did not know how to write a .lintr file.

Thanks for raising this. It is indeed important to make things easier for new users.

Similar:

• Edit user ~/.Rprofile
• Edit project .Rprofile
• Edit user ~/.lintr
• Edit project .lintr

It would be nice if we have something to make it easier for users to know how to edit these config files.

Related to r-lib/lintr#886

There are functions called usethis::edit_r_environ() and usethis::edit_r_profile().

However, if we want to edit files in a project, not the user, a directory without a .Rproj file is not considered a project by the usethis package and cannot be used.

We now have lintr::use_lintr() to help create a dummy file.
