[R] R equivalent to Matlab's Bayes net toolbox

I'm attending  summer School at UCLA (IPAM) on "probabilistics models of  
cognition". I have been an R-user since v. 1.4.1, but was trained in the  
frequentist tradition (as most psychologists!). I found that all faculty  
here use matlab and Murphy's bayes net toolbox. I have not had the need to  
use matlab before, and would love to stick to R for graphics models and  
bayesian modeling in general (even if it takes me extra time to cross-code  
the examples in matlab into R).

I'm trying to find an R equivalent to Matlab's Bayes net toolbox.

I have found packages 'deal' and 'gR', and played around with:

But I cannot really figure out how all these packages are integrated.  
Also, appendix B of 'bayesian AI' lists gR as "vaporware" (although this  
could well be outdated by now).

Is there any R news article on bayesian networks? It's hard to find,  
because I don't think the content of R-news is indexed in CRAN. I could  
download every issue and search the TOC, but it'd be time-consuming.

Even though the examples in the documentation in package 'deal' are good,  
they fall short. A good tutorial would be great.
What I'd like to know from you is whether R is a sensible choice or  
whether BNT is just easier and more mature.

Right now I could easily chose R or Matlab, since I have made little  
investment in any form of bayesian networks modeling; However, since I  
have a better background in R than in Matlab, I'd love to stay with R.

Any resources (mailing lists, books, tutorials) would be greatly  

Thanks a lot in advance,
