Usage

setChannelTypes(x, types)

Arguments

x

A PhysioExperiment object.

Examples

pe <- PhysioExperiment(
  assays = list(raw = matrix(rnorm(400), nrow = 100, ncol = 4)),
  colData = S4Vectors::DataFrame(label = c("Fz", "EOG1", "EMG1", "Oz")),
  samplingRate = 100
)

# Set all channels to same type
pe <- setChannelTypes(pe, "EEG")

# Set specific channel types by name
pe <- setChannelTypes(pe, c(EOG1 = "EOG", EMG1 = "EMG"))
