version 4 is on the way

10 September 2021

Version 4.0.0.0 of pomp is now available on the the package github repo.

This release contains a few backwardly incompatible changes, which are explained here. All of these have to do with the elementary function trajectory, which computes trajectories of the deterministic dynamical skeleton.


version 3.6 released

05 September 2021

pomp version 3.6 has been released to CRAN and will be available soon at a mirror near you. This release features improvements in the package manual, a few bug fixes, and some feature upgrades.

Highlights include:


version 3.5 released

30 July 2021

pomp version 3.5 has been released to CRAN and will be available soon at a mirror near you. The main feature upgrade concerns the reproducibility functions bake and stew, which cache calculation results. In previous versions, if the calculation was modified, or if any of its dependencies changed, it was necessary to manually delete the cache file to force recomputation. In the new release, these functions now now silently cache information about the calculation and its dependencies. If these are modified, recomputation is triggered. In addition, the user now has more control over the information that is returned. See the package manual for more details.

This release also fixes a bug in bsmc2 and upgrades the partrans function to make it easier to use with objective functions.

See the package NEWS for full details.


new versions of 'bake' and 'stew'

19 July 2021

The latest development version (3.4.5.0) is available for download on the pomp website. This release includes a major overhaul of the two reproducibility functions, bake and stew. These functions are used for caching the results of expensive calculations. In the past, if the cached calculation was modified, or if any of its dependencies changed, it was necessary to manually delete the cache file. As of version 3.4.5.0, pomp now silently caches information about the calculation and its dependencies. If these are modified, recomputation is triggered. See the package manual for more details.

To install from the package repository, do

install.packages("pomp",repos="https://kingaa.github.io/")

or
