Hi,

I am currently performing heart rate variability analyses on beat-to-beat
heart rate data using a non-parametric approach (AR power spectral density).
I am interested in decomposing a AR-spectrum into its components (main
outcomes of interest are the centre frequency and the power of the
bell-shaped spectral components) similar to this function in octave
http://www-2.nersc.no/~even/matlab/toolbox/biosig4octmat-2/tsa/ar_spa.m

I have searched R packages and forums for leads on how I might be able to do
this in R without success.
Any help pointing me in the right direction would be greatly appreciated.

Thank you very much,
Jessica
