Changes in version 0.99.0 - Submitted to Bioconductor. - First release. CorNetto builds knowledge-guided multi-omic correlation networks from normalized abundance data held in a MultiAssayExperiment, and provides: - group-specific correlation networks, and pre-analysis summaries of sample counts, missingness and feature counts; - two-group differential correlation by the Fisher z-difference test, either over all within-omic pairs or over candidate edges supplied by a prior-knowledge network; - node-level rewiring scores, with permutation reference distributions that report whether the result is a randomization p-value or a conditional ranking; - pathway-focused subnetworks, igraph conversion, and Cytoscape-ready node and edge export.
