Hello, Does anyone of you know if someone has programmed the Bry & Boschan routines in R? It's also known as the NBER method for identifying economic cycles peaks and troughs. Or do you know any method in R for indentifying peaks and troughs for times series. I tried turnpoints(), but I get too many turnpoints... It's a long shot, but I had to ask before programming it myself.
