the function can result in NA for two reasons. 1) the ID is not found in the presence data, which is accompanied by a warning and 2) the ID was not yet present if a referene date is specified

Examples

data(adv); data(advpres)
SEQ <- elo.seq(winner = adv$winner, loser = adv$loser, Date = adv$Date,
               presence = advpres)
lastdaypresent(SEQ, ID = "all", refdate = "2010-01-02")
lastdaypresent(SEQ, ID = "f", refdate = "2010-02-02")
