Sliding window connectivity

Computes connectivity matrices over sliding time windows.

Usage

slidingWindowConnectivity(
  x,
  window_size = 256L,
  step = 64L,
  method = c("correlation", "coherence", "plv"),
  ...
)

Arguments

x

A PhysioExperiment object.

window_size

Window size in samples.

step

Step size in samples.

method

Connectivity method: "correlation", "coherence", or "plv".

...

Additional arguments passed to connectivity function.

Value

A list with time-varying connectivity matrices.

Examples

set.seed(123)
pe <- PhysioExperiment(
  assays = list(raw = matrix(rnorm(1000 * 4), nrow = 1000, ncol = 4)),
  samplingRate = 100
)
dyn_conn <- slidingWindowConnectivity(pe, window_size = 200, step = 50)
