wrds_connect: Connect to WRDS

In wrds: Access 'Wharton Research Data Services' ('WRDS')

Connect to WRDS

Description

Establishes a connection to the WRDS PostgreSQL server using credentials stored securely in the system keyring.

Usage

wrds_connect(user_key = "wrds_user", password_key = "wrds_pw", keyring = NULL)

Arguments

user_key	Name of the keyring entry storing the WRDS username. Defaults to "wrds_user".
password_key	Name of the keyring entry storing the WRDS password. Defaults to "wrds_pw".
keyring	Optional keyring name. If NULL (default), uses the default keyring.

Details

Credentials must be set up before first use with wrds_set_credentials(). The connection uses bigint = "numeric" so that 64-bit integers from PostgreSQL are returned as doubles, which avoids overflow and works well with tidyverse functions.

Value

A DBIConnection object for the WRDS PostgreSQL database.
