version 3.3 released
21 March 2021
pomp version 3.3 has been released to CRAN and will be available soon at a mirror near you. This release contains changes to help other packages link to the pomp library. All of these changes will be invisible to the pomp user.
version 3.2 released
04 December 2020
pomp version 3.2 has been released to CRAN and will be available soon at a mirror near you. This release contains relatively minor improvements, primarily to the documentation.
The only significant user-visible changes concern the functions profileDesign, sliceDesign, runifDesign, and sobolDesign, which have been deprecated and will be removed in a future release.
They are replaced by profile_design, slice_design, runif_design, and sobol_design, respectively.
In addition, the behavior of profile_design has changed.
Previously, the same random (type="runif") or sub-random (type="sobol") sequence was used for all non-profile parameters.
The new behavior is that, for each profile slice, a distinct set of points is generated.
documentation improvements in version 3.1.1.7
05 August 2020
pomp development version 3.1.1.7 has just been released on the package github site. It contains a number of improvements to the package help pages. These are also available online (as the package manual).
version 3.1.1.1 released
19 July 2020
pomp development version 3.1.1.1 has just been released on the package github site.
This release introduces the profile_design function, which is intended to replace profileDesign.
The so-called profile design consists of a series of slices through a parameter space perpendicular to one or more coordinate axes.
The old behavior was to generate a single set of points in one of these slices (randomly according to a uniform distribution when type="runif" and according to a sub-random (Sobol’) sequence when type="sobol") and then copy these points across all slices.
Thus, in a projection perpendicular to the slices, all nprof generated points would lie atop one another.
The new behavior is to generate the points in each slice independently.
Thus, a projection perpendicular to the slices will display n*nprof points, where n is the number of slices.
For stylistic reasons, the other design functions, sliceDesign, runifDesign, and sobolDesign have been replaced by slice_design, runif_design, and sobol_design, respectively.
The older functions remain in place, but are deprecated and will be removed in a future release.
volunteer needed
09 July 2020
I’m looking for a volunteer who can maintain the pomp installation instructions for Mac users. Personally, I work pretty much exclusively on linux machines. I think I’m more or less able to keep up with the Windows installation instructions, but with respect to the Mac, I’m not keeping up. It seems I turned around and several things changed at once.
If there’s a Mac user out there, a veteran installer of pomp, who can edit/augment the Mac installation instructions on an ongoing basis, to keep up with advice from the R core team, probably including revising or replacing the gfortran installation instructions, it would a great service to the pomp community!
Please contact me if you’re interested.
