5.2.2.3

• This version adds the new basic component dinit for evaluating the probability density function of the initial-state distribution. There is a corresponding workhorse function, dinit().

• The constructor pomp now takes the optional argument nstatevars, which can be used to increase the dimension of the latent state-vectors created by rinit. By default, nstatevars = length(statenames), and nstatevars can only be used to increase, not to decrease, the dimension of the latent state process. Moreover, nstatevars has no effect if the rinit basic component is furnished as an R function.

• Name checking on internally-created vectors and arrays is less strict than previously. In particular, it is possible to have variables without names (i.e., "").

5.2.1.0

Changes in pomp version 5.2.1:

• reulermultinom now returns NA rather than NaN, in keeping with the behavior of rbinom. Thanks to John Drake for calling attention to this issue.

5.1.1.3

A bug in stew resulting in namespace conflicts has been repaired.

5.1.1.0

We no longer import from dplyr. Instead, we use data.table::rbindlist to bind data frames together.

5.1.0.0

Identical to CRAN version 5.1.

5.0.1.2

This is a bug-fix release.

5.0.1.1

In bake and stew, the archive directory will be created if it does not exist.

version 5.0.0.3

• We no longer import from plyr.

• The dimnames attributes of various arrays that appear in pomp, including arrays of observables, state variables, parameters, covariates, and so on, have been made uniform. In particular, when a dimension of an array corresponds to variables with different names, this dimension is itself named "name". Previously, its name was sometimes "variable" and sometimes "parameter". This change is meant to streamline interaction with the tidyverse.

• Some minor bugfixes.

4.7.0.1

Some improvements to the internal implementation and documentation of stateful objective functions.

Identical to version 4.7

• Functions with names.that.contain.dots that were been deprecated in version 4.5.1 are now defunct. Attempts to use such functions will generate an error with a message indicating the replacement function.
• plot now removes NA.
