Changes in version 0.2.4 - Improved vignettes Changes in version 0.2.3 - Added documentation explaining effectiveness of aggregation. - Improved clarity of user-facing error messages. - Removed reducible matrix examples from documentation. Changes in version 0.2.2 - Documentation updates: documentation more accessible with a gentler introduction - Minor vignette updates. - Added dedication. Changes in version 0.2.1 - Documentation updates: clarified help text and standardized references/DOIs. - Minor vignette formatting updates. Changes in version 0.2.0 Breaking changes - Renamed elasticity() to mpm_elasticity() to avoid name collisions with other demographic packages. Documentation - Simplified and streamlined function documentation across the package. Changes in version 0.1.1 Initial version - Added mpm_aggregate() and leslie_aggregate() for standard and elasticity-consistent aggregation in the lambda and R0 frameworks. - Added generation_time(), a function to compute generation time from matrix population models using either a λ-based or R0-based framework. - Added elasticity(), a function to compute elasticities of the dominant population growth rate (λ) or net reproductive rate (R₀) with respect to entries of matrix population models.
