Description Usage Arguments Value Examples
pretty.dates indentifies which unit of time the sub-intervals should be measured in to provide approximately n breaks. It then chooses a "pretty" length for the sub-intervals and sets start and endpoints that 1) span the entire range of the data, and 2) allow the breaks to occur on important date-times (i.e. on the hour, on the first of the month, etc.)
