epicR 1.0.0
Major changes
- Modularized C++ engine into separate compilation units
(
model_input.cpp, model_output.cpp,
model_events.cpp).
- Replaced hardcoded input values with JSON-based configuration files
(
inst/config/config_canada.json,
inst/config/config_us.json).
- Added multi-jurisdiction support (Canada and US).
- Added
simulate() function that manages sessions
automatically, replacing manual init_session() /
run() / terminate_session() workflow.
- Removed MI, stroke, and heart failure modules from the model.
New features
simulate() gains n_agents parameter for
setting population size.simulate() gains return_events option for
returning individual-level event data.- Real-time progress bar during simulation runs.
- User-level configuration management with
get_user_config(), set_user_config(), and
reset_user_configs().
- Validation functions now support jurisdiction-specific
comparisons.
- New
validate_exacerbation() function consolidates
exacerbation validation by sex.
- Added exacerbation counts by calendar time and sex to extended
outputs.
- Added cost tracking outputs (
cumul_cost_gold_ctime,
cumul_qaly_gold_ctime) to extended results.
Bug fixes
- Fixed out-of-bounds array access in
n_exac_by_medication_class (array sized [3]
but exac_status can be 1–4).
- Fixed event code inconsistencies and exacerbation counts per GOLD
stage.
- Fixed crash when using
simulate() with
return_events = TRUE.
- Fixed auto-termination logic to prevent premature session
cleanup.
Other improvements
- Reduced installed package size (compiled shared library reduced from
~6.5 MB to ~0.4 MB).
- Improved memory management in the C++ engine.
- Internal functions (
init_session(), run(),
terminate_session()) are no longer exported.
- Improved documentation and vignettes.
- Added comprehensive test suite.
