Default wrapper function for the GeneNet network inference algorithm





Numeric matrix with the microarray dataset to infer the network. Columns contain variables and rows contain samples.


GeneNEt uses an heuristic for learning statistically a causal network. It relies on a conversion of a network inferred through correlation into a partial correlation graph. Then, a partial ordering of the nodes is assigned by means of a multiple testing of the log-ratio of standardized partial variances. This allows identifying a directed acyclic causal network as a sub-graph of the partial correlation network.


GeneNet.wrap The function returns a matrix which is the weighted adjacency matrix of the network inferred by GeneNet algorithm. The shrinkage method used to estimate the partial correlation matrix is "static". - see ggm.estimate.pcor. The probability threshold is set to 0.8. - see ggm.estimate.pcor.
