aliases (PR#6614)

Submission from: (NULL) (130.132.33.212)



please define aliases for the 5 essential data set operations

  delete row
  insert row
  delete column
  insert column
  rename column

these are too difficult for novices as-is now, and the cost for doing this for
you would be very low.  if need be, define hints only, such as

dataset.del.row() <- function
   cat("to delete a row, do this...");


regards,
