Usage

downsample_physio(
  ep.physio,
  downsample_factor = 1,
  digital_channels = c("ttl_code", "ttl_onset", "Digital.*"),
  method = "subsample"
)

Arguments

ep.physio	An ep.physio object created by read_acq
downsample_factor	An integer factor used to subsample data
digital_channels	Column names or positions containing digital channels, These will be downsampled using the downsample_digital_timeseries function to use the within-chunk mode, rather than blind subsampling.
method	How to downsample the signal. The default is "subsample", which simply takes every nth sample from the original time series. The alternative is "decimate", which calls signal::decimate. This applies a low-pass filter before downsampling to avoid aliasing. At the moment, there are big ringing artifacts at the beginning...
