#' @description Generic for the \link[base]{as.data.frame} function

#' the data frame. Missing values are not allowed.
#' @param optional If TRUE, setting row names and converting column names
#' (to syntactic names: see \link[base]{make.names}) is optional. Note that all of R's
#' base package \code{as.data.frame()} methods use \code{optional} only for column names
#' treatment, basically with the meaning of
#' @param ... additional arguments to be passed to or from methods.
