bnlearn and TAN network

Hi Ross,

The output node is classFFB.  My understanding is that the model only
has one node linked directly to the output node:
][matureTreeData.ESTATE|classFFB].

Actually not, e.g.
[matureTreeData.YEAR|classFFB:matureTreeData.ESTATE] means
P(matureTreeData.YEAR | classFFB, matureTreeData.ESTATE). So all
variables depend on classFB.

I was looking for  a plot which shows the learned network, an example of
which I have attached.

That is the best you can get from bnlearn at the moment - although it
is possible in theory to produce a graph + barplots plot from
Rgraphviz. I have never managed to make it work, though.

Cheers,
    Marco
