Hi, I'm trying to install rjags and R2jags with R version 2.14.1 (2011-12-22) on Linux Mint 12 machine using software repository: deb http://cran.fhcrc.org/bin/linux/ubuntu oneiric/ jags seems to install OK, but rjags gives a weird error about not finding fprec symbol. Here is a history of the problem including several attempts to work around it. (Because of Ben Bolker's recent post, I first removed jags) sudo apt-get remove jags ## The following packages will be REMOVED: ## jags r-cran-rjags sudo apt-get install jags ## The following NEW pack...

Given that a number of us are housebound, it might be a good time to try to improve the approximation. It's not an area where I have much expertise, but in looking at the qbeta.c code I see a lot of root-finding, where I do have some background. However, I'm very reluctant to work alone on this, and will ask interested others to email off-list. If there are others, I'll report back.

...in R. My attempts to find "easy" workarounds have > not been successful, but I'll admit that other things took precedence. Well, the current development version of 'Rmpfr' on R-forge now contains facilities to enlarge the precision of the computations by a factor 'fPrec' with default 'fPrec = 1'; notably, instead of x %*% y (where the `%*%` cannot have more than two arguments) does have a counterpart matmult(x,y, ....) which allows more arguments, namely 'fPrec', or directly 'precBits'; and of course there are crossprod() and tcros...

I came to report this same bug and found it already in the trash, but I slightly disagree with that assessment. If it's not a bug, then perhaps it's a feature request. Comments at the end.
