This function converts data from a tbl_df() format into a xts format. Note that the dataframe must be a data.frame or tbl_df, and either the first column must be a valid date column, or there must be one column named date, Date or DATE to order by. tbl_xts also allows the user to specify the columns to be transformed to xts, as well as an option for spreading by a single character or factor type column. See the example for details.
