runjags (version 1.0.1-1)
Interface utilities for MCMC models in Just Another Gibbs
Sampler (JAGS) using parallel and distributed computing methods
Description
This package provides high-level interface utilities for
JAGS, either running locally (via the rjags package or using
multiple cores in parallel) or via distributed computing
clusters such as those provided by snow (a Simple Network Of
Workstations), Apple Xgrid distributed computing clusters (Mac
OS X 10.5-10.7 only), and possibly others via user specified
functions. The primary motivation is to facilitate running
relatively simple JAGS models to convergence, including
evaluating the performance of a model against simulated data,
and compatibility with the WinBUGS syntax of model files with
data and initial values lists. Runjags interface functions
also provide convenience wrappers for automatic control of
model convergence assessment and run length diagnostics,
calculation of relevant summary statistics, generation of trace
and density plots, calculation of DIC, and automatic retrieval
of R objects as data and initial values. Running of arbitrary
R commands (not involving JAGS) over Xgrid is also supported.
