Combine PhysioExperiment objects by channels

Source: R/PhysioExperiment-methods.R
cbindPhysio.Rd

Combines two PhysioExperiment objects by concatenating along the channel (column) dimension. Both objects must have the same number of time points and matching sampling rates.

Usage

cbindPhysio(x, y)

Arguments

x

A PhysioExperiment object.

y

A PhysioExperiment object to combine.

Value

A PhysioExperiment object with channels from both x and y, combined colData, and metadata from x.

Examples

pe1 <- PhysioExperiment(
  assays = list(raw = matrix(rnorm(200), nrow = 100, ncol = 2)),
  colData = S4Vectors::DataFrame(label = c("Fz", "Cz")),
  samplingRate = 100
)
pe2 <- PhysioExperiment(
  assays = list(raw = matrix(rnorm(200), nrow = 100, ncol = 2)),
  colData = S4Vectors::DataFrame(label = c("Pz", "Oz")),
  samplingRate = 100
)

# Combine channels
pe_combined <- cbindPhysio(pe1, pe2)
nChannels(pe_combined)  # 4
#> [1] 4
