-#' @description Take in input data frames and/or files containing raw data, and
-#' timezones, and output a Data object, roughly corresponding to a list where each cell
-#' contains all value for one day (see \code{?Data}).
+#' Acquire data as a Data object; see ?Data.
+#'
+#' Since series are given in columns (database format), this function builds series one
+#' by one and incrementally grows a Data object which is finally returned.
