Combine PhysioExperiment objects by time

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

Concatenates two PhysioExperiment objects along the time (row) axis. Both objects must have the same number of channels and matching sampling rates. Event onsets in y are offset by the duration of x.

Usage

rbindPhysio(x, y)

Arguments

x

A PhysioExperiment object.

y

A PhysioExperiment object to concatenate.

Value

A PhysioExperiment object with time points from both x and y concatenated, combined rowData, and merged events.

Examples

pe1 <- PhysioExperiment(
  assays = list(raw = matrix(rnorm(400), nrow = 100, ncol = 4)),
  samplingRate = 100
)
pe2 <- PhysioExperiment(
  assays = list(raw = matrix(rnorm(400), nrow = 100, ncol = 4)),
  samplingRate = 100
)

# Concatenate in time
pe_concat <- rbindPhysio(pe1, pe2)
length(pe_concat)  # 200
#> [1] 200
