series <-c(0,0,0,0,0,10,0,0,0,0,0,10,0,0,0,0,0,10,0,0,0,0,0,10,0,0,0,0,0,10 ,0,0,0,0,0,10,0,0,0,0,0,10,0,0,0,0,0,10,0,0,0,0,0,10,0,0,0,0,0,10)
Here ain this example after period 4 the pattern repeats. So we can say that the above series have a period of 4. Now my question is by using the function spec.pgram(series, log="no") we will get a graph of power vs frequency. Correct me if I am wrong. Now from this graph I want to determine the period of seasonality. How should I determine it?? -- View this message in context: http://r.789695.n4.nabble.com/help-spectral-analysis-spec-pgram-tp851439p2216079.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ 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.
