Create epochs using sliding window

Segments continuous data into overlapping epochs using a sliding window approach. This is useful for time-frequency analysis or when events are not available.

Usage

epochSliding(x, window, step = NULL, baseline = NULL)

Arguments

x

A PhysioExperiment object

window

Window size in seconds

step

Step size in seconds (default: window/2 for 50% overlap)

baseline

Optional baseline correction window as c(start, end) in seconds relative to epoch start. NULL for no correction.

Value

PhysioExperiment with epoched data

Examples

pe <- PhysioExperiment(
  assays = list(raw = matrix(rnorm(1000 * 4), nrow = 1000, ncol = 4)),
  samplingRate = 100)
# Create 0.5 second windows with 0.1 second step
epoched <- epochSliding(pe, window = 0.5, step = 0.1)
