I am looking for some help at removing low-frequency components from a signal, through Moving Average on a sliding window.
I understand thiis is a smoothing procedure that I never done in my life before .. sigh.

I searched R archives and found "rollmean", "MovingAverages {TTR}", "SymmetricMA".
None of the above mantioned functions seems to accept the smoothing polynomial order and the sliding window with as input parameters. Maybe I am missing something.

I wonder whether there is some building blocks in R if not even a function which does it all (I do not expect that much,though).
Even some literature references and/or tutorials are very welcome.

Thank you so much,
Maura
