durations.dive: Durations of time between each waypoint of a dive

In scuba: Diving Calculations and Decompression Models

Durations of time between each waypoint of a dive

Description

Extracts, or alters, the durations of each interval between waypoints during a dive.

Usage

durations.dive(d)
durations.dive(d) <- value

Arguments

d	A dive (object of class "dive").
value	A numeric vector containing durations in minutes.

Details

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 duration of the time interval between each successive pair of waypoints is returned by durations.dive. The assignment durations.dive(d) <- value alters these durations, provided the new vector value has the same length as the old one.

Value

durations.dive returns a numeric vector containing the durations of intervals between each waypoint, in minutes.
