Using a set of eigenvectors of matrices associated with a graph as coordinates
Usage
layout_with_eigen(g, type = "laplacian", ev = "smallest")
layout_igraph_eigen(g, type = "laplacian", ev = "smallest", circular)Arguments
- 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
Details
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.
Examples
library(igraph)
g <- sample_gnp(50, 0.2)
xy <- layout_with_eigen(g, type = "adjacency", ev = "largest")
xy <- layout_with_eigen(g, type = "adjacency", ev = "smallest")
xy <- layout_with_eigen(g, type = "laplacian", ev = "largest")
xy <- layout_with_eigen(g, type = "laplacian", ev = "smallest")
