...oking 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)...
