diveMove (version 1.2.2)

detDive-internal: Detect dives from depth readings

Description

Identify dives in TDR records based on a dive threshold.

Usage

.detDive(zdepth, act, dive.thr)

Arguments

zdepth

numeric vector of zero-offset corrected depths.

act

factor as long as depth coding activity, with levels specified as in .detPhase.

dive.thr

numeric scalar: threshold depth below which an underwater phase should be considered a dive.

Value

• A data frame with the following elements for .detDive
• dive.id
  Numeric vector numbering each dive in the record.
• dive.activity
  Factor with levels L, W, U, D, and Z, see .detPhase. All levels may be represented.
• postdive.id
  Numeric vector numbering each postdive interval with the same value as the preceding dive.

Examples

## Continuing the Example from '?calibrateDepth':
utils::example("calibrateDepth", package="diveMove",
               ask=FALSE, echo=FALSE)
dcalib		# the 'TDRcalibrate' that was created

tdr <- getTDR(dcalib)

## Extract the gross activity from an already calibrated TDR object
gross.act <- getGAct(dcalib)
detd <- diveMove:::.detDive(getDepth(tdr), gross.act[[2]], 3)
