Chris, if you really want to use the stl() function, one possible solution is to do
my.ts=ts(my.ts,start=1800,frequency=2). Rogerio --- Original Message --- From: Christoph Scherber <Christoph.Scherber_at_agr.uni-goettingen.de> Date: Wed, 10 Oct 2007 16:16:39 +0200 Dear R users, I am trying to ´detect´ the trend in an artificial time series created by the simple function x=seq(pi,10*pi,0.1) my.ts=0.1*x+sin(x) my.ts=ts(my.ts,start=1800) plot(my.ts) I have tried stl(my.ts), but because I don´t have ´replications´ at every time point, this somehow doesn´t work. How could I best detect the trend in the ts? I would very much appreciate any help! Thanks a lot in advance Christoph (using R 2.6.0 on Windows XP) ______________________________________________ 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.
