time_calc: block-averaged time

In USGS-R/GDopp: processing of ADV data

Description

time average for within block

Usage

time_calc(data.sen, window.idx, freq = 32)

Arguments

data.sen	a data.frame created with load.ADV, with the window.idx column
window.idx	window.idx column from adv data.frame.
freq	the frequency (Hz) of the measurements

Details

a GDopp function for averaging time observations from ADV sensor (1Hz).
assumes one second spin-up for high-frequency measurement, and a likely incomplete final second for high frequency.

Value

a vector of block mean time

Examples

## Not run: 
folder.nm <- system.file('extdata', package = 'GDopp')
file.nm <- "ALQ102.dat"
data.adv <- load_adv(file.nm=file.nm, folder.nm =folder.nm)
window.adv <- window_adv(data.adv,freq=32,window.mins=10)
data.sen <- load_sen(file.nm="ALQ102.sen", folder.nm = folder.nm)

time_calc(data.sen,window.adv$window.idx,freq=32)

## End(Not run)
