Examples

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

# Rename channels
pe <- renameChannels(pe, c("Fz", "Cz"), c("F3", "C3"))
channelNames(pe)
#> [1] "F3" "C3" "Pz" "Oz"
