        day: The day number.  The data includes only data from
             day 307 and early 308.

       time: The time of day formatted as hour-minute.

       temp: The body temperature in degrees Celsius.

      activ: The dichotomized activity indicator. `1' indicates
             that the beaver is outside of the retreat and
             therefore engaged in high-intensity activity.

   SSUUMMMMAARRYY::

        The `beaver' data frame has 100 rows and 4 columns.  It
        is a multivariate time series of class `"rts"' and also
        inherits from class `"data.frame"'.

        This data set is part of a long study into body temper-
        ature regulation in beavers.  Four adult female beavers
        were live-trapped and had a temperature-sensitive
        radiotransmitter surgically implanted.  Readings were
        taken every 10 minutes.  The location of the beaver was
        also recorded and her activity level was dichotomized
        by whether she was in the retreat or outside of it
        since high-intensity activities only occur outside of
        the retreat.

        The data in this data frame are those readings for one
        of the beavers on a day in autumn.
