Using a set of eigenvectors of matrices associated with a graph as coordinates
layout_with_eigen(g, type = "laplacian", ev = "smallest") layout_igraph_eigen(g, type = "laplacian", ev = "smallest", circular)
g |
igraph object |
type |
matrix to be used for spectral decomposition. either 'adjacency' or 'laplacian' |
ev |
eigenvectors to be used. Either 'smallest' or 'largest'. |
circular |
not used |
The layout_igraph_* function should not be used directly. It is only used as an argument for plotting with 'igraph'. 'ggraph' natively supports the layout.
matrix of xy coordinates
