In other words, I want to plot and fit models for each month separately. Taking the example of http://a-little-book-of-r-for-time-series.readthedocs.org/en/latest/src/timeseries.html births <- scan("http://robjhyndman.com/tsdldata/data/nybirths.dat";) birthstimeseries <- ts(births, frequency=12, start=c(1946,1)) birthstimeseries plot.ts(birthstimeseries) birthstimeseriesHW <- HoltWinters(birthstimeseries) plot(birthstimeseriesHW) How to proceed the plotting and HoltWinters smoothing considereing only Januarys, Februarys, etc. separately. Thanks in advance.
