#' @param tofactor if this is equal to numeric 1 or \code{TRUE}, characters will be converted to factors. Otherwise no 
#' conversion will be done. The default is not to convert.
#' @param keepblank if characters are not to be converted to factors, this argument decides how to deal with 
#' blank cells in character columns. If it is numeric 1 or \code{TRUE}, a blank cell will be converted
#' to "" (size 0 string). Otherwise it is viewed as \code{NA} (default).
#' @param sep a single character to differentiate cells of a table. The default value should be used when 
#' your data is from Excel.
