i have this kind of plot, i'm trying to use peakDetector in order to find the positions of the first peak and the first valley that are very close.
I need to leave out them e start finding the max and min value after these initial ones. I use peakdetector but it doesn' t give me the position of all the peak (and valley).
here is what I obtain (for the peaks):
