Both are pretty ancient bugs which we probably should have found aeons ago.
Releases 0.1.3 and 0.1.4 made it to CRAN

(Eddelbuettel and Francois, 2011, JSS) and thereby allows for easier and more

The two NEWS entries are below:
Courtesy of CRANberries, there are also diffstat reports for 0.1.3. and 0.1.4. As always, more detailed information is on the RcppSMC page,Changes in RcppSMC version 0.1.4 (2014-05-02)
