Figure 2 - Estimation of the ad hoc distance threshold. Example of output obtained using the function adhocTHR with default settings (30 arbitrary distance thresholds, linear fit and an estimated relative identification error (RE) of 5%). The following message was given by the function: "for a RE of 0.05 use a threshold of 0.0334".
