_D_e_s_c_r_i_p_t_i_o_n:

     Reynolds (1994) describes a small part of a study of the long-term
     temperature dynamics of beaver Castor canadensis in north-central
     Wisconsin.  Body temperature 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.

_U_s_a_g_e:

     data(beavers)

_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.

     The variables are as follows:

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

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

     _t_e_m_p Measured body temperature in degrees Celsius.

     _a_c_t_i_v Indicator of activity outside the retreat.

_N_o_t_e:

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