), the function will use the following order defined in the guesser:list( quarter_partial_dates = c("Y", "Ym", "Yq"), world_digit_months = c("Yq", "ymd", "ydm", "dmy", "mdy", "myd", "dym", "Ymd", "Ydm", "dmY", "mdY", "mYd", "dYm"), world_named_months = c("dby", "dyb", "bdy", "byd", "ybd", "ydb", "dbY", "dYb", "bdY", "bYd", "Ybd", "Ydb"), us_format = c("Omdy", "YOmd") )
