swimming_effort: Compute swimming effort

In SESman/rbl: Biologging tools for diving predators in R

Description

Compute swimming effort

Usage

swimming_effort(x, fs = 16, fc = c(0.4416, 1.0176), rms = FALSE)

Arguments

x	3 axes acceleration table with time in the first column and acceleration axes in the following columns. Variables must be entitled "time" for time, "ax", "ay", and "az" for x, y and z accelerometer axes.
fs	sampling frequency of the input data (Hz).
fc	Cut-off frequencies for the butterworth band pass filter (Hz)
rms	Should the root mean square be used (instead of mean of absolute values) when averaging the acceleration to 1 Hz ?

Details

Only Y accelerometer axe is used to compute swimming effort.

Value

returns a vector of swimming effort values at 1 Hz.
