Examples

tp_data <- chicken_generator(1)
tp_data_mapper <- mapper.sta(dat = tp_data[,2:4],
                               filter_values = tp_data$Y,
                               num_intervals = 10,
                               percent_overlap = 70)
tp_spread <- spread_measure(tp_data_mapper, tp_data$Group)
