Angle between agent and group members

Finds the angle at which the group members are located compared to the agent. Uses the predicted positions of the group members for this.

Usage

get_angles(
  agent_idx,
  agent_group,
  position,
  orientation,
  predictions,
  centers,
  any_member = TRUE
)

agent_idx: Numeric denoting the position of the agent in the prediction matrix p_pred.
agent_group: Numeric vector with the group membership of all pedestrians.
position: Numeric vector denoting the current position of the agent.
orientation: Numeric denoting the current orientation of the agent.
predictions: Numeric matrix with shape N x 2 containing predicted positions of all pedestrians that belong to the social group of the agent.
centers: Numerical matrix containing the coordinates at each position the object can be moved to. Should have one row for each cell.
any_member: Logical denoting whether to consider the angles of all group members (TRUE) – effectively saying that it doesn't matter which group member the agent can see, as long as they can see one – or whether to only consider the nearest group member (FALSE). Defaults to TRUE.

Numeric vector containing the relative angle of the group member(s) compared to the orientation of the agent within a given cell in centers.
