MetaRVM 2.1.0

CRAN release: 2026-03-26

  • Added simulation_mode (deterministic/stochastic) and nrep support in configuration parsing and run metadata.

  • Improved stochastic reproducibility: provided random_seed is honored, and a seed is generated/stored when missing.

  • Updated stochastic transition splitting to use binomial draws for integer compartment flows (n_EIpresymp, n_IsympH, n_HR).

  • Improved metapopulation infection-flow indexing consistency for destination- specific force of infection in n_SE_eff and n_VE_eff.

  • Added bounded vaccination and transition safeguards to reduce overdraw risks (for example, capping applied vaccination by available susceptible count and guarding zero effective population in force-of-infection calculations).

  • Added integer row allocation for stochastic mixing flows (S and V) using floor-plus-residual adjustment so row totals are conserved.

  • Added regression tests for stochastic seed behavior, nsim * nrep instance counts, and row-allocation conservation checks for S/V mixing.

  • Enhanced results helper APIs:

    • MetaRVMResults$plot() now provides direct trajectory plotting before summarization.
    • MetaRVMSummary$plot() now supports instance-trajectory plotting.
    • summarize() uses a more efficient single-pass grouped aggregation.

MetaRVM 2.0.0

CRAN release: 2026-03-19

  • Subpopulation categories are now user-defined from population_data$initialization; non-reserved columns are detected automatically.

  • Improved checkpoint restore behavior in parse_config(): when restore_from is provided, population_data$initialization can be used as mapping-only metadata (without N, S0, I0, etc.).

  • Improved validation messages for category filters: invalid category names now list available categories, and invalid category values now list valid values for the selected category.

  • Improved format_metarvm_output() handling of population_id and dynamic column selection for user-defined categories.

  • Updated documentation and vignettes to reflect user-defined subpopulation categories and checkpoint restore behavior.
