First of all excuse me for reviving this very old thread - if it is the
preferred way in this forum/ mailinglist, I will start a new one instead.
I'm a computational biologist programming in C++ and I'm actually not
familiar with R. But I wrote a small program to analyse Win-/OpenBugs output
(CODA) according to this paper:
http://dx.doi.org/10.1016/j.anbehav.2004.08.011 . As I'm working with Mac
and Linux (Kubuntu 9.10 ?Karmic Koala? at the moment) and WINbugs only runs
on Windows natively (as it's name says), I want to switch to JAGS instead.
Now I have the problem to change the WinBugs formatted model and data into
JAGS/R formatted ones, which is quite difficult without knowing the actual
differences between R and S(-PLUS) programming languages. (The latter one
seems to be the basis of WinBugs' format.) I'm not completely sure whether
"bugs2jags" can be applied to this case, but when I tried to execute it with
the main example from the above mentioned paper (see attachment), it showed
this error message:
> library(coda)
Lade n?tiges Paket: lattice
> bugs2jags("WinBugs.txt","Jags.txt")
Fehler in parse(file = file) :
