pomp version 5.5 has been released to CRAN and is making its way to a mirror near you.
This release contains a few feature enhancements and some changes to the internals.
Feature enhancements
- There is now access to ordinary B-spline basis functions (and their derivatives) at the C snippet level.
It will still almost always be preferable to construct a spline basis once and pass it to pomp functions using
covar=covariate_table(...)
, but this functionality may occasionally be useful. bspline_eval
is now deprecated as part of the pomp C API.- Stateful objective functions (class
objfun
) now behave as if they are objects of classpomp
. This makes it easier to work with them in plotting results, extracting information from the fitted model object, etc.
Internal changes
- The C-level functions
set_pomp_userdata
andunset_pomp_userdata
have been deprecated and will be removed in a future release. Using the latter now generates a warning that can be safely ignored.
