i need to perform "Time Series Analysis" using Fourier Analysis/Technique on temperature data of 17 years. Their are four columns in it "Years", "Months", "Days" and "Temperature in C". I need basic Tutorial/web-link or any thing useful which helps me step by step to do the Time Series. Thanks
A very basic introduction to Fourier analysis, using R, is given here. It shows R code to apply the fft function and plot outputs.
