Causal lowpass filtering with decimation

Description

Causal lowpass filtering with decimation

Usage

lpfilter(y, wgts, ndec = 1)

lpfilter.dec(y, frq = 1, ndecs = c(2, 5), plt = FALSE, ...)

Arguments

y	numeric
wgts	numeric; convolution filter weights
ndec	integer; the decimation factors to use
frq	integer; the sampling frequency of y
plt	logical; should the decimation stages be plotted?
...	additional parameters to ts in the case y does not have class 'ts'.

Details

Applies a single-sided convolution filter with the filter weights (wgts) to the data (y). The decimation factor is set with ndec but is only applied when ndec>1.
