Resample all streams onto a single common-rate view

Source: R/MultiRatePhysioExperiment-class.R
resampleToCommon.Rd

Interpolates every stream onto a shared time grid at rate, honouring each stream's start offset on the master clock, and returns a single PhysioExperiment whose channels are the union of all streams' channels (prefixed with the stream name). Grid positions before/after a stream's coverage are NA.

Usage

resampleToCommon(x, rate = NULL)

Arguments

x

A MultiRatePhysioExperiment.

rate

Target sampling rate in Hz (default: the clock reference rate).

Value

A single-rate PhysioExperiment with an "aligned" assay.

Examples

kin <- PhysioExperiment(
  S4Vectors::SimpleList(raw = matrix(rnorm(100 * 2), 100, 2)), samplingRate = 100)
emg <- PhysioExperiment(
  S4Vectors::SimpleList(raw = matrix(rnorm(1000 * 2), 1000, 2)), samplingRate = 1000)
mr <- MultiRatePhysioExperiment(kin = kin, emg = emg)
aligned <- resampleToCommon(mr, 1000)
dim(SummarizedExperiment::assay(aligned, "aligned"))
