-#' @description \code{binarize()} serializes a matrix or CSV file with minimal overhead,
-#' into a binary file. \code{getDataInFile()} achieves the inverse task: she retrieves
-#' (ASCII) data rows from indices in the binary file. Finally,
-#' \code{binarizeTransform()} serialize transformations of all data chunks; to use it,
-#' a data-retrieval function must be provided, thus \code{binarize} will most likely be
-#' used first (and then a function defined to seek in generated binary file)
-#'
-#' @param data_ascii Either a matrix or CSV file, with items in rows
-#' @param indices Indices of the lines to retrieve
-#' @param data_bin_file Name of binary file on output (\code{binarize})
-#' or input (\code{getDataInFile})
+#' @param data_ascii Either a matrix (by columns) or CSV file or connection (by rows)
+#' @param data_bin_file Name of binary file on output of (\code{binarize})
+#' or input of (\code{getDataInFile})
