Interpolate bad channels

Replaces bad channels with interpolated values from neighboring channels.

Usage

interpolateBadChannels(
  x,
  bad_channels,
  method = c("average", "spline"),
  output_assay = "interpolated"
)

Arguments

x

A PhysioExperiment object.

bad_channels

Integer vector of channel indices to interpolate.

method

Interpolation method: "average" or "spline".

output_assay

Name for the output assay.

Value

Modified PhysioExperiment with interpolated channels.

Examples

pe <- PhysioExperiment(
  assays = list(raw = matrix(rnorm(300 * 3), nrow = 300, ncol = 3)),
  samplingRate = 100
)
pe <- interpolateBadChannels(pe, bad_channels = 2, method = "average")
