peak detection

previously I wrote...
    THere's the peaks package which will do some peak detection, or 
'peaks' in the simecol package. Or msc.peaks.find in caMassClass,

I'm madly trying to remember what spectral package I found which has a 
tool similar to msextrema but returns a couple more useful lists 
describing the data and the results...

  Found it   pastecs:turnpoints   is a nice function which, as I said, 
returns lists of maxima and minima along with a lot of other good stuff.
