I am trying to use your package gRain using your book on graphical models in R to do predictions, I have 38 columns of vectors all factors and built a bayesian network using iamb() function, then I used the following command to make a grpahNEL (However, I have 38 nodes and 106 edges) using BN<-iamb(data1) BN.gr<-as(amat(BN),"graphNEL") Then when I am using the following command to make a grain object I got the following errors, any thoughts? Thanks a lot for your help in advance. BN.grain<-grain(BN.gr,data=data1) Error in function (classes, fdef, mtable) : unable to find an inherited method for function "nodes", for signature "graphNEL", "missing"
Are you aware you posted to the mailing list rather than to the package maintainer? Uwe Ligges
