I am calling fft and getting a "non-numeric" error: + fit <- lm(Quantity ~ DayOfYear, .sublist) + # Make the time series + x <- as.numeric(rep(0,512)) + x <- merge(residuals(fit), x) + # Transform range to -pi - pi + x <- x - pi + x <- x * (2 * pi)/(max(x) - min(x)) + fft(x)
Error in fft(x) : non-numeric argument How can I tell what the non-numeric argument is? There is only one argument. What am I doing wrong? Thank you.
