.t as parameter in the
propensity functions.This release contains a major rewrite of the internal code, to make sure the code is readable and that the algorithm doesn’t continuously update the local environment.
MAJOR CHANGE: Instead of passing "D",
"ETL", "OTL", or "BTL" to
ssa(), it is expected to pass ssa.d(),
ssa.etl(), ssa.otl(), or
ssa.btl(). This cleans up parameter setting clutter in the
ssa() function.
MAJOR CHANGE: Rewrite ssa.*() and
ssa.*.diag() as ssa_step.ssa_*() and
ssa_step_diag.ssa_*() S3 functions.
MAJOR CHANGE: Do not save the current state in the function environment. Instead, simply save it in a local variable.
MAJOR CHANGE: Precompile propensity functions instead of evaluating them as R code at each iteration.
MAJOR CHANGE: Clean up and merge ssa.run(),
ssa.terminate(), ssa.check.args() and
ssa.check.method() into ssa().
MAINTAINER: Maintainer has been changed to Robrecht Cannoodt.
DOCUMENTATION: Documentation was roxygenised and markdownised.
DOCUMENTATION: Port demo’s to vignettes.
DOCUMENTATION: Added NEWS and README.
DOCUMENTATION: Remove ’s from examples.
MINOR CHANGE: Many functions were refactorised in order to clean up the code.
MINOR CHANGE: Functions which are marked “Not intended to be invoked stand alone.” are no longer being exported.
BUG FIX: Fix warning and potential error in OTL.
No changes, it seems.
MINOR CHANGE ssa.run(): Throw error when propensity
values are negative.
DOCUMENTATION: Add radioactiveDecay demo
MINOR CHANGE ssa(): Move chunks of code to separate
functions ssa.check.args(), ssa.check.method()
and ssa.run().
DOCUMENTATION: Expand documentation of many functions.
MINOR CHANGE ssa(): Minor changes to how the states
and the propensity functions are evaluated.
DOCUMENTATION: Rework demos.
MINOR CHANGES: Minor updates to package to bring it up to date with the JSS manuscript.
DOCUMENTATION: Added the metapopulation SIRS model described in the JSS manuscript as a demo model to the package
BUG FIX: bug fixes.
DOCUMENTATION: fixed error in url of package home page.
MINOR CHANGES: Revised how model parameters are passed to the
ssa() (per Ben Bolker’s suggestion). Model parameters are
now passed directly to ssa() as a named vector and hence
they do not have to be declared in the global environment.

These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
