Hi!
Just a quick PR so Drill doesn't error out when using
lead()orlag()with dbplyr SQL translation. Before this, the value fordefault(NAby default) would get passed in as a third argument (e.g.LAG(variable1, 1, NA)) which causes Drill to throw an error that refers users to this Jira ticket.This implementation does pass through the value for
n, which is1Lby default. Drill doesn't currently support any other value besides 1, but this implementation works and will be forwards-compatible if the limitation gets lifted in the future.
