Folks: I have a big data set representing a sort of spectrogram. Basically it is a two-column matrix: one column is frequency, another is a power of the sort. The whole thing is arranged as a spectrum. I need to locate the spectral lines. Typical length of spectrum about 100000. Presumably, there are hundreds of peaks in the spectrum. Forgetting for a time being all the intricacies of the concept of "peak", is there anything simple around in the s-plus world to determine the locations of the spectral peaks? Thanks Kamil
