Description

Find the dives start and end

Usage

dive_delim(obj, thres.dur = c(300, 3000), thres.depth = 15, warn = TRUE,
  ...)

Arguments

obj	An object of class 'ses', 'statdives' or 'tdr' with time and depth variables named "time" and "depth".
thres.dur	The minimum time (seconds) a dive should last to be considered as a dive. If thres.dur has two elements the second is the maximum time (seconds) a dive should last to be considered as a dive. If thres.dur = NULL then this threshod is ignored.
thres.depth	The depth threshold (in sensor units): diving period implies greater values.
warn	Should a Warning column be added ?
...	Other arguments

Value

A data frame with the following variable: indice of period start, indice of period end, type of period, duration (s), the dive number and a optional Warning column. Attributes of the data frame include some information about the processing.
