[R] peak detection

[Carl Witthoft]

	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...

Hi Joe,

Just for info, I've done this in the past by applying lowess followed by 
diff to a vector, then identifying points with change of sign in the diffs.
