spikegornik: Despike ADV data using the GoringNikora phase-space procedure

In jsta/adv: Process Acoustic Doppler Velocimeter Data

Description

Despike ADV data

Usage

spikegornik(fpath, outpath = NULL, maxcounter = 5, plotting = TRUE,
  plotwin = c(1, nrow(dt)))

Arguments

fpath	file.path to ADV output where the column of interest is named "Speed"
outpath	file.path to save results. optional.
maxcounter	numeric number of smoothing passes
plotting	logical output progress to plots?
plotwin	numeric vector of length 2 specifying the plotting window

Details

This function is nearly a direct translation of the MacVicar et al. (2014) SpikeGoringNikora.m script from MATLAB to R. Single value spikes are not removed if they are the same as a linear interpolation between adjacent points. Remove measurements where the SNR > 5 per the ADV manual?

Value

data.frame datetime of class POSIXct and speed of class numeric
