netplot {c3net} | R Documentation |
netplot
takes the inferred mutual information matrix and plots a network wrt nonzero elements of the matrix - see details.
netplot(gnet)
gnet |
A symmetric squared mutual information matrix that is inferred as final connection matrix, where i,j th element is the mutual information I(i,j) or I(j,i) between variables i and j. The nonzero elements may also be 1. Diagonal is all zero. |
A labelled undirected network is plotted wrt the row (column) names of the input matrix. When plotted, select "Layout" and then "Fruchterman-Reingold" and "OK" to get a better view. To remove labels, select "View" and deselect "Labels". To change the colors or size of nodes and edges, from "Select", click on "all edges" or "vertices" and on the network right click on nodes and change color or size.
netplot
returns an undirected network.
