Following this change, we recommend that users explicitly name their arguments rather than relying on argument order, since the argument order has changed with this update. Update your existing code accordingly if you notice unexpected behaviour.plot_life_cycle now includes a logical argument show_gv which allows users to print the graphViz code constructed by the function to the screen. This is useful for use elsewhere, or for debugging plots.entropy_k is being deprecated. We change the function name to life_elas and recommend use of the new functions entropy_k_age and entropy_k_stage for Leslie and Lefkovitch matrices respectively. See the article by de Vries et al (2023) for the rationale for this change.plot_life_cycle to ensure that nodes are placed in the correct order. Additional argument node_order also allows nodes to be placed in any arbitrary order.life_expect_var and life_expect_mean to ensure that outputs are consistent (as vectors).is_leslie_matrix function to detect a Leslie matrix.leslie_collapse function to aggregate a Leslie matrix to a desired dimension. This function is similar to mpm_collapse but it will ensure that the returned aggregated matrix is also in the form of a Leslie matrix. Code contributed by Richard A. Hinrichsen (@hinrich62).life_expect_var (#193) corrected (contribution from Chrissy Hernández, @chrissy3815). Note that life_expect_mean and life_expect_var now function slightly differently. Be aware!entropy_d entropy_k shape_rep and shape_surv can now accept matrices directly. In previous versions, these functions required input of lx and/or mx trajectories, but now the functions can optionally use mpm_to_... functions to create these vectors internally (#174).remove_final argument to mpm_to_table function. This allows users to optionally remove the final row of the life table to prevent the artificial inflation of mortality/hazard caused by the fact that the final age-class is assumed to be closed (and hence all individuals must die).Fixed an error in the entropy_d function, which calculates Demetrius's entropy.
Added two methods to calculate generation time in gen_time: average parent-offspring age difference & expected age at first reproduction (#183).
