thresholdr is a collection of auxiliary functions that serve to calculate latencies between events in longitudinal data:
latency_one_threshold()takes a matrix with longitudinal measurements and timepoints and returns a matrix with (i) latencies until a given threshold was reached and (ii) status (endpoint met versus censored).latency_two_thresholds()takes a matrix with longitudinal measurements and timepoints and returns a matrix with (i) latencies between two measurements and (ii) status (endpoint reached versus censored).calculate_volume()calculates the volume of an ellipsoid object given width and length.survival_custom()provides a customized survival plotting function.
