Merge two PhysioExperiment objects by combining channels

Horizontally concatenates the channels (columns) of two PhysioExperiment objects that share the same sampling rate. Channel labels are prefixed to avoid name collisions.

Usage

mergePhysio(x, y, prefix = c("x_", "y_"))

Arguments

x

A PhysioExperiment object.

y

A PhysioExperiment object.

prefix

Character vector of length 2: prefixes added to channel labels from x and y respectively (default c("x_", "y_")).

Value

A single PhysioExperiment with the columns of both inputs.

Details

Both objects must have the same number of time points (rows) and the same sampling rate. Only the first assay of each object is merged.

Examples

pe1 <- PhysioExperiment(
  assays = list(raw = matrix(rnorm(100 * 4), nrow = 100)),
  colData = S4Vectors::DataFrame(label = paste0("A", 1:4)),
  samplingRate = 500
)
pe2 <- PhysioExperiment(
  assays = list(raw = matrix(rnorm(100 * 4), nrow = 100)),
  colData = S4Vectors::DataFrame(label = paste0("B", 1:4)),
  samplingRate = 500
)
merged <- mergePhysio(pe1, pe2)
