 
Hello,
 
I'm trying to built a model for a time-series analysis with an periodic
term for seasonality.
I've tried both harmonic (package spatstat) and periodicSpline (package
splines). The former don't allow a periodic constraint, while I've not
been able to use the latter within a dataframe with several repetition
of the month series along the years.
 
Can you suggest some options or new commands?
 
Thanks a lot
