1d:T644,# Guess if a character vector contains Date values, and convert them to date ```r date_guess_convert(data, error_tolerance, timeframe, orders) ``` ## Arguments - `data`: A `` - `error_tolerance`: A `` between 0 and 1 indicating the proportion of entries which cannot be identified as dates to be tolerated; if this proportion is exceeded, the original vector is returned, and a message is issued; defaults to 0.4 (40 percent). - `timeframe`: A `` of 2 values of type ``. If provided, date values that do not fall within this timeframe will be set to `NA`. - `orders`: A `` or `` of characters with the date codes for fine-grained parsing of dates. This allows for parsing of mixed dates. If a `` is supplied, that `` will be used for successive tries in parsing. When this is not provided (`orders = NULL`), 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") ) ``` ## Returns A `` with the following two elements: the input data frame where the character columns with date values have been converted into ``, and a vector of column names where there are numeric values that can also be of type Date. 1e:T49a,M7.49933 0.25C3.49635 0.25 0.25 3.49593 0.25 7.50024C0.25 10.703 2.32715 13.4206 5.2081 14.3797C5.57084 14.446 5.70302 14.2222 5.70302 14.0299C5.70302 13.8576 5.69679 13.4019 5.69323 12.797C3.67661 13.235 3.25112 11.825 3.25112 11.825C2.92132 10.9874 2.44599 10.7644 2.44599 10.7644C1.78773 10.3149 2.49584 10.3238 2.49584 10.3238C3.22353 10.375 3.60629 11.0711 3.60629 11.0711C4.25298 12.1788 5.30335 11.8588 5.71638 11.6732C5.
