Dear Colleagues,
For those of you working with accelerometer and magnetometer data, I wanted to call your attention to a new R package called TrackReconstruction designed to perform dead reckoning on the data and visualize the results. The package includes a vignette with some additional information on dealing with large data sets using PERL prior to import into R, color mapping of the results with bathymetry data and finally how to make animated movies of the tracks. The package does not have functions to analyze behavior, a major focus of accelerometer research in our field. To that end, I'm keen to expand the utility of the package from other contributors who don't want to go through the hassle of creating their own R package, please contact me [email protected] if you are interested. This R package is not the only package for this type of analysis. There is another R package called animalTrack that does essentially the same thing but with a slightly different implementation and some nice alternative features. In addition there is an add-in to IGOR Pro that does the deadreckoning and an additional add-in from Kentaro Sakamoto called Ethographer that does behavioral analysis, and of course Colin Ware's TrackPlot that is an amazing visualization tool. There may be others I'm not aware of. Cheers, Brian
