	     range returns a vector containing the minimum and max-
	     imum of all the values present in its arguments.  If
	     na.rm is FALSE, an NA value in any of the arguments
	     will cause values of NA to be returned, otherwise NA
	     values are ignored.
	
	     This definition of range should not be confused with
	     the sample range.
