nLTT-package Package providing functions to visualize the normalized Lineage-Through-Time statistic, and calculate the difference between two nLTT curves
abc_smc_nltt A function to perform Approximate Bayesian Computation within a Sequential Markov Chain (ABC-SMC), for diversification analysis of phylogenetic trees.
check_input_event_times Checks that event times are correct
check_phylogenies Check if the input is a valid collection of one or more phylogenies
check_step_type Check if the step type is valid
check_time_unit Check if the time unit is valid
default_params_doc This function does nothing. It is intended to inherit is parameters' documentation.
