InterpolateNIHR function

Linear or Spline interpolator for build the sample heart rate signal

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)

Arguments

• HRVData: Data structure that stores the beats register and information related to it
• freqhr: Sampling frequency
• method: "linear" interpolation or "spline" monotone interpolation
• verbose: Deprecated argument maintained for compatibility, use SetVerbose() instead

Returns

Returns HRVData, the structure that contains beat positions register, associated heart rate instantaneous values also, and filtered heart rate signal equally spaced
