I use WinBUGS by way of R (R2WinBUGS).
So,I want to use GeoBUGS like this or another
(batch / script etc.. not GUI.
I would like to use R,if possible).
What do you mean by using GeoBUGS? If you mean the
spatial functions
(car.normal, etc.) you can make use of them as any
other function in WB
by including them in your WB code and using
R2WinBUGS to run it. If you
mean the adjacency tool, then you can check function
nb2WB() in R to get
the adjacency matrix in the same way as in GeoBUGS
from a nb object (see
the example therein). If you want to display the WB
results in a map you
can use spplot(), for example.
Hope this helps.
