    Body Temperature Series of Two Beavers
}
\usage{data(beavers)}
\format{
    The \code{beaver1} data frame has 114 rows and 4 columns on body
    temperature measurements at 10 minute intervals.

    The \code{beaver2} data frame has 100 rows and 4 columns on body
    temperature measurements at 10 minute intervals.

\description{
    Reynolds (1994) describes a small part of a study of the long-term
    temperature dynamics of beaver \emph{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. 
}
\arguments{
    \item{day}{
    Day of observation (in days since the beginning of 1990),
    December 12-13 (\code{beaver1}) and November 3-4 (\code{beaver2}).
    }
    \item{time}{
    Time of observation, in the form \code{0330} for 3:30am
    }
    \item{temp}{
    Measured body temperature in degrees Celsius
    }
    \item{activ}{
    Indicator of activity outside the retreat
    }
}
\note{
    The observation at 22:20 is missing in \code{beaver1}.
