Dear R Community,

I am happy to introduce the next release of the *dclone* package (see R Journal, 2(2): 29-37, 2010) which now includes a suite of functions for parallel computations:

The *dcmle* package defines S4 classes around infrastructure provided by the dclone package to make package development with data cloning for hierarchical models easy as a breeze.

The testing suite of the two packages now includes 30 examples (see listDcExamples() ).

library(dcmle)
sourceDcExample("seeds")
cl <- makePSOCKcluster(3)
parLoadModule("glm")
m <- dcmle(seeds, n.clones=c(1,2,4), cl=cl, partype="parchains") stopCluster(cl)
m

I am grateful for the feedback and support provided by a growing user base. Special thanks to Martyn Plummer for exposing RNG handling in rjags for better integration, and to Khurram Nadeem for catching the most annoying bugs on the test run.

Cheers,

Peter
