Simulate a synthetic PhysioExperiment for demos and tests

Deterministic (seeded) synthetic signals per modality. Clearly synthetic — for exercising a pipeline's mechanics, not for making claims.

Usage

pp_simulate(
  modality = c("eeg", "emg", "eda"),
  seed = 1L,
  n_channels = NULL,
  duration = NULL,
  sampling_rate = NULL
)

Arguments

modality

One of "eeg", "emg", "eda".

seed

Integer RNG seed (fixed so pipelines stay reproducible).

n_channels, duration, sampling_rate

Optional geometry overrides.

Value

A PhysioExperiment (time x channels) with a raw assay.

Examples

if (requireNamespace("PhysioCore", quietly = TRUE)) {
  pe <- pp_simulate("eeg")
}
