## iBBiG performs bi-clustering of binary matrices

### Description

iBBiG is a bi-clustering algorithm, optimized for module discovery in sparse noisy binary genomics data. We designed iBBiG to have high specificity and thereby minimize the false positive rate when discovering new classes; the iterative approach employed in iBBiG is able to discover weak signals, even if they are potentially masked by stronger ones.

### Examples

    #create simulated datasets
    binMat<-makeArtificial()
    binMat
    plot(binMat)
    res<- try(iBBiG(binMat@Seeddata, nModules=10))
    plot(res)
    res

    ## Subset a cluster

    res[4]
    res[1:2]

    ## As iBBiG extends the class Biclust can use Biclust functions on it
    ## View the rows and columns of an iBBiG object

    ## Create a list of matrices, one for each cluster
    Modules<-bicluster(res@Seeddata, res)
    length(Modules)
    lapply(Modules, dim)

    # Or extract a list of a specific cluster
    M1<-bicluster(res@Seeddata, res, 1)
    dim(M1[[1]])
    str(M1)
    M1[[1]][1:5,1:3]
