c14_date_list

The c14_date_list is the central data structure of the c14bazAAR package. It's a tibble with set of custom methods and variables. Please see the variable_reference table for a description of the variables. Further available variables are ignored.
If an object is of class data.frame or tibble (tbl & tbl_df), it can be converted to an object of class c14_date_list. The only requirement is that it contains the essential columns c14age and c14std. The as function adds the string "c14_date_list" to the classes vector of the object and applies order_variables(), enforce_types() and the helper function clean_latlon() to it.
