Apply a FIR-1 bandpass filter a signal. Can low- or high-pass filter by specifying 0 for low or >= Nyquist for high.

Description

Apply a FIR-1 bandpass filter a signal. Can low- or high-pass filter by specifying 0 for low or >= Nyquist for high.

Usage

fir1Bandpass(
  x,
  TR = 2,
  low = 0.009,
  high = 0.08,
  n = 250,
  plotFilter = FALSE,
  forward_reverse = TRUE,
  padx = 0,
  detrend = 1
)

Arguments

x	The time series to be filtered
TR	The sampling frequency in seconds
low	The lower filter cutoff in Hz. Fluctuations below this frequency will be filtered out
high	The upper filter cutoff in Hz. Fluctuations above this frequency will be filtered out
n	The order of the filter coefficients. Should probably leave this alone in general
