WebAfter finding a fitting low-pass filter, the high-pass filtering is as simple as subtracting the low-pass filtered values from y: highpass <- y - predict (lowpass.loess, x) lines (x, highpass, lwd = 2) This answer comes late, but I hope it helps someone else struggling with similar problem.

Low-pass filters remove high-frequency noise and thus smooth the data. Band-pass filters allow only certain frequencies and filter everything else out. Notch filters remove certain frequencies.

That argument must be a boolean (i.e. True or False). By setting it to False, you are selecting the behavior of the filter to be a high-pass filter (i.e. the filter does not pass the 0 frequency of the signal).
