An algorithm to obtain a heart rate signal with equally spaced values at a certain sampling frequency
InterpolateNIHR(HRVData, freqhr = 4, method = c("linear", "spline"), verbose=NULL)
Returns HRVData, the structure that contains beat positions register, associated heart rate instantaneous values also, and filtered heart rate signal equally spaced
Data structure that stores the beats register and information related to it
Sampling frequency
"linear" interpolation or "spline" monotone interpolation
Deprecated argument maintained for compatibility, use SetVerbose() instead
