rollwinrms: Rolling RMS

In AkselA/R-rollfun:

Description

Wrapper for rollconv() offering a quick rolling windowed RMS

Usage

rollwinrms(x, w, ...)

Arguments

x	numeric vector; data
w	integer or numeric vector; width or shape of the rolling RMS window
na.pad	logical; should the ends be padded with NA?
B	prime; smoothness as used by the FFT algorithm

Examples

w <- 50
weights.para <- winweights(w, type="parabolic")
weights.hann <- winweights(w, type="hann")

plot(weights.hann, type="l", ann=FALSE)
lines(weights.para)

data(xyz2)
yy <- xyz2

plot(yy, col="grey", type="l")
lines(rollwinrms(yy, weights.hann, partial=TRUE), col="blue", lwd=2)
lines(rollwinrms(yy, weights.para, partial=TRUE), col="green", lwd=2)
lines(rollwinrms(yy, w, partial=TRUE), col="red", lwd=2)
