Add a code of conduct — use_code_of

Adds a CODE_OF_CONDUCT.md file to the active project and lists in .Rbuildignore, in the case of a package. The goal of a code of conduct is to foster an environment of inclusiveness, and to explicitly discourage inappropriate behaviour. The template comes from https://contributor-covenant.org, version 2: https://contributor-covenant.org/version/2/0.

use_code_of_conduct(path = NULL)

Arguments

path	Path of the directory to put `CODE_OF_CONDUCT.md` in, relative to the active project. Passed along to `use_directory()`. Default is to locate at top-level, but `.github/` is also common.

Details

If your package is going to CRAN, the link to the CoC in your README must be an absolute link to a rendered website as CODE_OF_CONDUCT.md is not included in the package sent to CRAN. use_code_of_conduct() will automatically generate this link if (1) you use pkgdown and (2) have set the url field in _pkgdown.yml; otherwise it'll link to https://contributor-covenant.org/version/2/0.
