rjuliabugs
Interface to 'JuliaBUGS.jl' from R
Provides an R interface to the 'JuliaBUGS.jl' package (< https://github.com/TuringLang/JuliaBUGS.jl>) for Bayesian inference using the BUGS modeling language. Allows R users to run models in Julia and return results as familiar R objects. Visualization and posterior analysis are supported via the 'bayesplot' and 'posterior' packages.
rjuliabugs 
rjuliabugs is an R package that provides a bridge between R and JuliaBUGS, the BUGS-style Bayesian modeling interface developed in Julia as part of the Turing.jl probabilistic programming ecosystem.
JuliaBUGS allows users to define models using the familiar BUGS syntax while leveraging the speed and flexibility of the Julia language. It enables automatic translation of BUGS code into modern probabilistic programs that run efficiently with advanced inference engines such as Hamiltonian Monte Carlo (HMC) — all accessible via Turing.jl.
With rjuliabugs, R users can run BUGS models/code through JuliaBUGS
and take advantage of the inference algorithms available in Turing.jl,
without leaving the R environment. This not only provides a seamless
path to adopt faster (including
parallelization)
and more flexible sampling methods but also allows integration with R’s
extensive post-processing ecosystem (e.g., bayesplot, posterior,
coda). It lowers the barrier for existing BUGS users to adopt modern
Bayesian tools without abandoning their existing model codebase.
Installation
You can install the development version of rjuliabugs from GitHub with:
# install.packages("remotes")
remotes::install_github("MateusMaiaDS/rjuliabugs")
⚠️ Loading the package:
When starting a R session for the first time, after loading the package
rjuliabugs and before running any function, we recommend to run
rjuliabugs::setup_juliaBUGS() to build all Julia setup in R and
install any needed dependencies. We recommend this initially as it an be
time-consuming. See ?rjuliabugs::setup_juliaBUGS for more details.
For further guidance, there articles in this page which summarize most
of the FAQ and additional instructions for installing Julia and setting
rjuliabugs, troubleshooting, and running rjuliabugs in parallel. We
recommend the reading of them before working with rjuliabugs:
