pomp version 2.1 released to CRAN

01 June 2019

I have just released pomp version 2.1 to CRAN. For the last six months, this has been available on the pomp website as the package pomp2.

Because it is not fully backward-compatible, pomp version 2 is being made available temporarily as the pomp2 package. Hopefully, most of you will have been using pomp2 for some time now, but if you find yourself needing to update old codes and workflows for the new version, have a look at the upgrade guide, which summarizes all the changes in version 2.

If you have pomp2 on your system, you should now remove it entirely, and replace all references to pomp2 in your codes with references to pomp.

As always, please don’t hesitate to bring questions, conundrums, puzzles, paradoxes, bugs, and feature requests, to my attention via by raising an Issue.


Upgrade Guide updates

23 December 2018

The pomp Version 2 Upgrade Guide has been revised. It now includes before-and-after examples of codes rewritten for pomp version 2. This is meant to help you revise pomp version <2 codes to take advantage of the new features.

As a reminder, an alpha-release preview of pomp version 2 is available as pomp2 on the pomp website. Do

install.packages("pomp2",repos="https://kingaa.github.io")

to install it. It is possible to have both pomp (version <2) and pomp2 installed simultaneously during workflow migration.

Around the middle of 2019, pomp2 will be renamed pomp and uploaded to CRAN as version 2.1. From that point forward, there will be no support for older versions of pomp.


Getting Started with pomp2

22 December 2018

The “Getting Started with pomp” vignette has been completely rewritten for pomp version 2. If you are new to pomp, or want to get up to speed on the changes coming in pomp version 2, have a look! The vignette is available here.


pomp version 2 released as pomp2

15 December 2018

Version 2 of pomp, with major improvements, is on its way! Because it is not fully backward-compatible, pomp version 2 is being made available temporarily as the pomp2 package. pomp2 is not available on CRAN but source and binaries can be downloaded from the pomp website. See the installation page for instructions.

pomp2 will be phased out, replaced by version 2 of pomp, around the middle of 2019. At that point, pomp versions <2 will no longer be supported.

It is recommended that users begin making the transition to version 2 now. An upgrade guide is available to help you transition your codes to the new version. In the interim period, you can have both pomp and pomp2 installed on your system simultaneously.
