Hi Mike, here's a sample of my data so that you get an idea what I'm working with.
http://r.789695.n4.nabble.com/file/n3618615/SampleDataSet.txt SampleDataSet.txt Also, I've uploaded an image showing a sample graph of daily soil moisture by treatment. The legend shows IP, IP+, PP, PP+ which are the 4 treatments. Also, I've included precipitation to show the soil moisture response to precip. http://r.789695.n4.nabble.com/file/n3618615/MeanWaterPrecipColour2ndSeasonOnly.jpeg I have used ANOVA previously, but I don't like it for 2 reasons. The first is that I have to average away all of the interesting variation. But mainly, it becomes quite cumbersome to do a separate ANOVA for each day (700+ days) or even each week (104 weeks). Thanks for your help, -Justin -- View this message in context: http://r.789695.n4.nabble.com/Time-series-analysis-with-treatment-effects-statistical-approach-tp3615856p3618615.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.
