6.4.0.0

This release contains only one minor feature upgrade: the coef function can now extract parameters by name from a listie, i.e., a list of pomp objects or objects that derive from pomp objects (created via concat for example).

6.3.1.0

This release includes a minor feature enhancement. coef can now retrieve parameters by name from a listie (i.e., a concat-enated list of pomp objects).

6.3.0.0

identical to 6.3

6.2.1.0

The built-in examples that use simulated data add a seed argument to allow changing the simulated data.

6.2.0.0

Identical to version 6.2 on CRAN.

6.1.1.1

The basic Kalman filter (kalmanFilter) has been refactored, with a roughly 3-fold speed up.

6.1.0.1

This release fixes some errors in the documentation.

6.1.0.0

Identical to version 6.1 on CRAN.

6.0.5.0

It is now possible to specify more than one lag in the ivp function, which is evaluated only when the mif2 perturbations are specified. See ?mif2.

6.0.4.0

• The new function append_data appends a data frame to an existing CSV file (creating the file if it does not exist). This facilitates keeping a database of parameter-space explorations.
• The new function eeulermultinom gives the expectation of an Euler-multinomial random variable.
