Check WRDS PostgreSQL credentials — wrds_check

Attempts a small WRDS PostgreSQL connection using RPostgres. The return value is a data frame so it can be printed or inspected in setup scripts.

Usage

wrds_check_credentials(
  wrds_id = NULL,
  password = NULL,
  prompt = interactive(),
  save = TRUE,
  passfile = NULL
)

wrds_id: Optional WRDS username override.
password: Optional password. If omitted, a matching .pgpass entry is preferred. When .pgpass has no matching entry, an existing WRDS_PASSWORD environment variable is used before an interactive prompt. PostgreSQL may also use PGPASSWORD or another libpq-supported mechanism when no password is passed to the connection.
prompt: If TRUE, prompt interactively for a WRDS PostgreSQL password when no password was supplied and no matching .pgpass entry exists.
save: If TRUE, save a supplied or prompted password to .pgpass after a successful WRDS connection test.
passfile: PostgreSQL password-file path. Defaults to PGPASSFILE when set, otherwise the platform default password-file path.
