Arguments

emg

Numeric vector or matrix of EMG data (time x channels).

emg_sampling_rate

EMG sampling rate (Hz).

mocap_length

Target number of MoCap samples.

mocap_sampling_rate

Target MoCap sampling rate (Hz).

method

Interpolation method passed to stats::approx().

Value

Matrix of aligned EMG data with mocap_length rows.
