Hi, I have a time series given as a couple of vectors: one of POSIXt dates and the other of values. I am looking for a seasonal pattern and I want to plot annual segments of the series aligned by months. For example if my data spans Jan-96 - Dec-97 I want to have two graphs on a single plot as functions of day of the year. How can I do this?
