Initial Angle of Trajectory
I was wondering if the mousetrap package in R was capable of producing the initial angle of the trajectory. This is a metric I've seen in Coco and Duran, (2016). They define it as:
"(a) initial degree (the degree of deviation from vertical after the mouse trajectory leaves a 50-pixel radius from the starting point, same as Buetti and Kerzel (2009)), where positive values indicate angles towards the incorrect target"
Thanks for any help you can provide. The mousetrap package has been a huge boon to my research.
