Details

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