Details

This function sends a GET request to the FDA openFDA API. It supports caching via the memoise package to avoid redundant calls, and respects a rate limit between successive API requests.

If the API request fails, returns no matches, or returns an error status code, the function returns NULL with an informative message.

• report_id: Unique identifier for the adverse event report

• date_received: Date FDA received the report

• country: Country where event occurred

• serious: Is it serious? ("Yes", "No", or original API value / NA)

• patient_sex: Patient sex ("Male", "Female", "Unknown", original API value, or NA)

• patient_age: Patient age at onset (as returned by API) or NA
