A numeric vector containing elapsed times in minutes. |
An object of class "dive" represents a scuba dive. It is
created by the function dive. A dive is defined as a
series of waypoints occurring at specified depths and times. The
elapsed time at each waypoint is returned by times.dive. The
assignment times.dive(d) <- value alters these elapsed times,
provided the new vector value has the same length as the old one.
times.dive returns a numeric vector containing the elapsed
times at each waypoint, in minutes.
