Extracts a time window from the signal based on start and end times in seconds.

Usage

extractWindow(x, tmin, tmax)

Arguments

x

A PhysioExperiment object.

tmin

Start time in seconds.

tmax

End time in seconds.

Value

A PhysioExperiment object containing only the samples within the specified time window, with preserved channel and event metadata.

Examples

pe <- PhysioExperiment(
  assays = list(raw = matrix(rnorm(1000), nrow = 1000, ncol = 4)),
  samplingRate = 100
)

# Extract 2 to 5 seconds
pe_window <- extractWindow(pe, tmin = 2, tmax = 5)
duration(pe_window)  # approximately 3 seconds
