Details

As recommended by the authors of the openalexR package,

Before we go any further, we highly recommend you set openalexR.mailto option so that your requests go to the polite pool for faster response times. If you have OpenAlex Premium, you can add your API key to the openalexR.apikey option as well. These lines best go into .Rprofile with file.edit("~/.Rprofile").

options(openalexR.mailto = "example@email.com")
options(openalexR.apikey = "EXAMPLE_APIKEY")"
