Graph analysis in r
WebGraphical Data Analysis in R. R is believed to be the best at data visualization for good reason. R base packages come with functions like the hist() function, the boxplot() function, the barplot() function, etc. that can render a single type of graph. They also include the incredible plot() function that can render multiple kinds of graphs depending on the input … Web14. There are various packages for representing directed and undirected graphs, incidence/adjacency matrix, etc. in addition to graph †; look for example at the gR Task view. For visualization and basic computation, I …

WebTitle Graph Theory Analysis of Brain MRI Data Description A set of tools for performing graph theory analysis of brain MRI data. It works with data from a Freesurfer analysis (cortical thickness, volumes, local gyrification index, surface area), diffusion tensor tractography data (e.g., from FSL) and resting-state fMRI data (e.g., from DPABI). WebFeb 27, 2015 · 13. I am looking to group/merge nodes in a graph using graph clustering in 'r'. Here is a stunningly toy variation of my problem. There are two "clusters". There is a "bridge" connecting the clusters. Here is a candidate network: When I look at the connection distance, the "hopcount", if you will, then I can get the following matrix :
