Dear Kevin,
I am admittedly not into Bayesian networks, but in any case the 10 SNPs limitation sounds a bit surprising. However, the error you encounter is quite package-specific. I think you may want to ask your question directly to deal's maintainer, in case you would not find an answer here.
I don't know of any package that would implement Bayesian networks specifically for genetic data.
Best regards,
Thibaut.

Dear all,
I am now trying to use Bayesian network to analyze my SNP data,
associating 20 SNPs with one phenotype (plasma cholesterol levels). I
want to use deal package to find the markov plane of my phenotype. I
have 3575 records. After trying the deal package, I can not go through
coomand----jointprior (). It is said "Error in array(1, Dim) : 'dim'
specifies too large an array".
I reduced the number of SNP to 10 and I can continue. When I try
"result<-heuristic(my.data1.nw,my.data1,my.data1.prior,restart=2,degree=
10,trace=TRUE)". It was said that "[Heuristic [Autosearch Error in
phi[[y]] : attempt to select less than one element". So, I can not get
the results.
I hope someone could help me with it. Am I using the right package?
Thanks in advance,
Kevin
