FFT - (STATS) - is this correct?
Hello,
I have calculated the fourier transform of the series enclosed at the end of this message, by doing:
library(stats)
x <- readLines("file1.txt")
x.num <- as.numeric(x)
ft.x.num <- fft(x.num)
My question is: why is the first value (Real) of ft.x.num that big? (954.833870) all the other values are much smaller. Am I doing something wrong?
Could you please help me to
