Check out ?turnpoints in the pastecs library.
to see the data structure you get back. It identifies the peaks
and pits and other associated information.

Subject: [R] [Q] Newbie (continued.. at least I got R running allready :-)
a week ago, I posted a newbie question in data smoothing &
maximum-extraction with R. I got quite a lot of response, but I'm still
kinda stuck with it...
I'll restate the problem : i got a datafile with 2400 measuerements (every
250msec) of a CO2 measurement device, capturing the breath of a subject. I
uploaded such a sample here :
now I wish to figure out where each breath expiration ceiling takes place ,
as shown on this graph :
I'm kinda stuck on how to get this running in R.
I really hope someone can help me out. If you guys can get me running, I
promise to promote R as often as I can here on our faculty (which still uses
Statistica for almost everything)
thanks a million in advance !
