This is a wrapper that computes the periodogram. Usage The periodogram is very easy to implement in R, but before we do we need to simulate some data. The code below first uses the set.seed command so R will produce the same "random" numbers each time. Then it creates a 32 normally distributed numbers and 32 points of a sine wave with a normalized frequency of 0.4 and a amplitude of 2. Some R Issues The Fast Fourier Transform in R doesn’t quite give a direct estimate of the scaled periodogram.

Then it creates a 32 normally distributed numbers and 32 points of a sine wave with a normalized frequency of 0.4 and a amplitude of 2. This file is perhaps a good starting point since it is a self-contained example of a Lomb-Scargle periodogram analysis of a 20-point cosine curve with even spacing over a 120 minute period. Run the script from a local file: source("cosine.R") or directly from this page (copy and paste this line into R): regression technique is used as periodogram bar. This proceeding incorporates analogues to most of the existing periodograms and introduces several new techniques.
