EMD: A Package for Empirical Mode Decomposition and Hilbert Spectrum
Donghoh Kim and Hee-Seok Oh , The R Journal (2009) 1:1, pages 40-46.

The concept of empirical mode decomposition (EMD) and the Hilbert spectrum (HS) has been developed rapidly in many disciplines of science and engineering since Huang et al. (1998) invented EMD. The key feature of EMD is to decompose a signal into so-called intrinsic mode function (IMF). Furthermore, the Hilbert spectral analysis of intrinsic mode functions provides frequency information evolving with time and quantifies the amount of variation due to oscillation at different time scales and time locations. In this article, we introduce an R package called EMD (Kim and Oh, 2008) that performs oneand twodimensional EMD and HS.
