Hi all 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 :

Hi all I'm a programmer at the psychology dept, and last week, I was asked to write an application to analyze some result data from CO2 measurement experiments. I don't want to reinvent the wheel, so before I start custom coding in C, I'd though to look around a bit and bumped into R on freshmeat. basically, it is a 2-column data sheet, with timings on col1 and CO2 value on col2.
