[R] Multiple periodicities

[Miguel A. Arranz]

Derar all,

This is a problem that I am unable to solve. I am interested in analyzing some 
high-frequency data which show two periodicities (periods 5 and 260), It is 
clear how to estimate models with one periodicity with arima() but I have not 
been able to include both periodicities. Is there some good way to handle tis 
kind of problem?

Thanks in advane,

Miguel A.
