Two days ago I started my journey with R, and right now I'm struck on Holtwinters, and have no idea, what I'm doing wrong. So now, I'll show step by step what I've been doing. Actually it is a part of "Introducy Time Series with R". 1) I download data from http://www.massey.ac.nz/~pscowper/ts/motororg.dat due to port blockage. Save it as motororg.txt 2) Inserting this code: Motor.dat <- read.table("motororg.txt", header = T) attach(Motor.dat) Comp.hw1 <- HoltWinters(complaints, beta = 0, gamma = 0) 3) Baang! Error here. "Error in decompose(ts(x[1L:wind], start = start(x), frequency = f), seasonal) : time series has no or less than 2 periods" 4) Actually it has, and I turned it on with attach command? Motor.dat complaints 1 27 2 34 3 31 4 24 5 18 6 19 7 17 8 12 9 26 10 14 11 18 12 33 13 31 14 31 15 19 16 17 17 10 18 25 19 26 20 18 21 18 22 10 23 4 24 20 25 28 26 21 27 18 28 23 29 19 30 16 31 10 32 24 33 11 34 11 35 13 36 27 37 18 38 20 39 21 40 6 41 9 42 29 43 12 44 19 45 14 46 19 47 16 48 23 Can you tell me what I am doing wrong? PS I tried to make complaints.ts as well but I didn't work either. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
