Dear all, it might not be a R-related question, however, I would appreciate if anyone could suggest a mathematical/statistical framework that integrates graphs and arrays, and potentially has a R implementation. to give an example : given a graph of interactions (gene1 --- gene2, gene3 --- gene5, etc), where each gene has set of features (eg expression, activity), to classify the subgraphs based on the features of its nodes. thanks very much, bogdan [[alternative HTML version deleted]]
