#' @param ds data set
#' @param record.id name or column number of id variable, moved to first row of
#' data dictionary, character of integer. Default is "record_id".
#' @param form.name vector of form names, character string, length 1 or length
#' equal to number of variables. Default is "basis".
#' @param field.type vector of field types, character string, length 1 or length
#' equal to number of variables. Default is "text.
