In tomjscox/GPPFourier: Calculate Gross Primary Production (GPP) from O2 Time Series

Description

Plot amplitude or argument of Fourier transform of a time series

Usage

plotF(x, dt = 1, units = "days", xlab = NULL, ylab = NULL,
  detrend = FALSE, add = FALSE, argument = FALSE, ...)

Arguments

x	Time series
dt	Time time interval, used to calculate frequencies
units	Time unit, default = "days"
xlab	x-label of plot. Default: f [d-1]" "f [cycles per day]"
ylab	y-label of plot. Default: |F(x)|, or Arg(F(x)) when argument=TRUE
detrend	If TRUE, series is detrended first. Default=FALSE
add	If TRUE, plot is added to existing plot
argument	If TRUE, plot the argument in stead of the modulus
...	Arguments passed to plot()

Value

A plot of the amplitude of the Fourier transform, calculated with fft(). No zero-padding or tapering is performed.
