Check whether WRDS credentials are available

Usage

wrds_credentials_available(
  wrds_id = NULL,
  password = NULL,
  prompt = interactive(),
  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.
passfile: PostgreSQL password-file path. Defaults to PGPASSFILE when set, otherwise the platform default password-file path.

TRUE if wrds_check_credentials() can open a WRDS PostgreSQL connection, otherwise FALSE.

wrds_credentials_available(prompt = FALSE)
#> [1] TRUE
