pomp version 0.53-1 released

pomp version 0.53-1 is now available on CRAN and coming soon to a mirror near you.

This is a major new feature release. Some highlights are:

It is now much easier to accelerate code through the use of compiled code.
pomp can now take snippets of C code directly as definitions of the various basic functions. This is accomplished through the use of a new Csnippet function. See the “sir” demo for a demonstration.

Features that facilitate multiple PMCMC and ABC chains have been added. There are c methods to combine abc and pmcmc objects. Running conv.rec on an abc, pmcmc, abcList, or pmcmcList object now produces coda mcmc and mcmc.list objects, respectively. Diagnostic plots are produced by running plot on such objects. Package coda is now a dependency of pomp. This package provides various generic MCMC diagnostics.
The transform argument for pmcmc and abc has been removed.
nlf now returns an S4 object of class nlfd.pomp with a logLik method for extracting the log quasi likelihood and a $ method for extracting arbitrary components.
It thus behaves like pomp's other inference methods.
The package manual and tutorials are no longer included with the package source. Instead, links are provided to the pomp website. The package help pages have been revisited for accuracy and completeness.

This software has been made possible by support from the U.S. National Science Foundation (Grants #EF-0545276, #EF-0430120), by the “Inference for Mechanistic Models” Working Group supported by the National Center for Ecological Analysis and Synthesis (a Center funded by N.S.F. (Grant #DEB-0553768), the University of California, Santa Barbara, and the State of California), and by the RAPIDD program of the Science & Technology Directorate, Department of Homeland Security and the Fogarty International Center, U.S. National Institutes of Health.
