Hello, I am having trouble constructing a time series object for my data. This is because the frequency is irregular: one year, there may be only 100 individuals, another 200. There are 100 measurements for every individual. I have the observations in a data frame with the year that they were taken from as a factor.
I would like to plot the top 10 mean measurements for each year and connect them with a line, to measurements in the same category. I would also like to try using linear filtering and exponential smoothing on the measurements to look for patterns, in particular synchronized drastic changes in measurement values. Are all the time-series analysis functions inappropriate because of the irregular frequency in my data? I looked at the reference manual, and it seems that even building the tsp attribute manually would require providing a frequency argument. It's quite possible that I have some very wrong ideas about time series analysis, as I am just beginning to study the subject. Thanks for any help, --Marco ______________________________________________ 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.
