Hello! I'm collecting data on a refrigerator that I'm using to cure meat. Specifically I am collection humidity and temperature readings. The temperature readings look sinusoidal (due to the refrigerator turning on and off).
I'd like to calculate the frequency and period of the wave so that I can determine if modifications I make to the equipment are increasing or decreasing efficiency. Unfortunately, I'm pretty new to R, so I'm not sure how to figure this out. I *suspect* I should be doing an fft on the temperature data, but I'm not sure where to go from there. Here is a graph I'm producing: http://i.imgur.com/WpsDi.png Here is the program I have so far: https://github.com/tenderlove/rsausage/blob/master/graphing.r I have posted a repository with a SQLite database that has the data I've collected here: https://github.com/tenderlove/rsausage Any help would be greatly appreciated! -- Aaron Patterson http://tenderlovemaking.com/
