distanceToTarget: Calculates distances to a target point

In BioTrajectory: Image Processing Tools for Barnes Maze Experiments

Calculates distances to a target point

Description

Given a dataset of points, it computes the Euclidean distances from each point to a specified target point. The function also identifies contiguous segments of points that fall within a specified radius around the target.

Usage

distanceToTarget(data, target, targetRadious = 0)

Arguments

data	An object of class 'trajectory' containing a collection of points with coordinates.
target	A numeric vector representing the coordinates of the target point.
targetRadious	A numeric value indicating the radius around the target point. Points within this radius are considered to be close to the target. Default is 0.

Value

A list containing:

distance	A numeric vector of distances from each point in 'data' to the 'target'.
r	A list with two components: 'start', indicating the starting indices of contiguous segments of points within the target radius, and 'length', indicating the lengths of these segments.
target_radious	The radius around the target point.
