     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_r_g_u_m_e_n_t_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_o_r_m_a_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_o_t_e_:

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