DiffGraph: an R package for identifying gene network rewiring using differential graphical models.

Abstract

We develop DiffGraph, an R package that integrates four influential differential graphical models for identifying gene network rewiring under two different conditions from gene expression data. The input and output of different models are packaged in the same format, making it convenient for users to compare different models using a wide range of datasets and carry out follow-up analysis. Furthermore, the inferred differential networks can be visualized both non-interactively and interactively. The package is useful for identifying gene network rewiring from input datasets, comparing the predictions of different methods and visualizing the results. The package is available at https://github.com/Zhangxf-ccnu/DiffGraph. leouyang@szu.edu.cn. Supplementary data are available at Bioinformatics online.
