If you run devtools::check() again, now, your final line should report: Since we’re saying that our package will be using the MIT license, we need to ensure there’s an associated LICENSE file which we can do by executing usethis::use_mit_license() which will create the necessary files and ensure the License field in the DESCRIPTION file is formatted properly.
To prove this, use the R console to run devtools::check() and - after some rather verbose output - you’ll see the following lines at the end: > checking DESCRIPTION meta-information. Īt this point we still do not have a “perfect” R package.
