        Reynolds (1994) describes a small part of a study of
        the long-term temperature dynamics of beaver Castor
        canadensis in north-central Wisconsin.  Body tempera-
        ture was measured by telemetry every 10 minutes for
        four females, but data from a one period of less than a
        day for each of two animals is used there.

        data(beavers)

   AArrgguummeennttss::

        day: Day of observation (in days since the beginning of
             1990), December 12-13 (`beaver1') and November 3-4
             (`beaver2').

       time: Time of observation, in the form `0330' for 3:30am

       temp: Measured body temperature in degrees Celsius

      activ: Indicator of activity outside the retreat

   FFoorrmmaatt::

        The `beaver1' data frame has 114 rows and 4 columns on
        body temperature measurements at 10 minute intervals.

        The `beaver2' data frame has 100 rows and 4 columns on
        body temperature measurements at 10 minute intervals.

   NNoottee::

        The observation at 22:20 is missing in `beaver1'.
