My brain is complete mush today.

But I needed to squeeze in a Skype meeting this morning with my long-distance undergrad, who has been determinedly plugging away at learning the basics with R. We have two main tasks left with the current stage of data analysis, which we basically need to translate from English into syntax. The first is figuring out how to read in a bunch of files from a bunch of directories. This should be straightforward.

The second task is one I'd been scratching my head over. When recording cricket activity, I set up the timelapse video to record 4 crickets at a time. Our tracking software assigns individual numbers to individuals, but for various reasons individual crickets wind up having between 1 and 10 different numbers assigned to them. So, how to separate out data for each individual cricket? I'd been thinking of coming up with a method to subset the track files by the assigned ID numbers. This would require figuring out how to import a ragged data file, then figuring out a kind of complicated reference scheme.

But then today C pointed out that because the crickets are spatially separated from each other, it would probably be a whole lot simpler to just subset based on each cricket's xy coordinates. We don't expect cricket 1 to ever show up in the area occupied by cricket 2, unless something went seriously wrong with the setup (nothing did).

Foreheadslap to self. Good job, undergraduate! You rock.

This startup is a VERY good idea. I need to pay a visit.
