emphasizes a hidden group structure if it exists in the graph. Calculates a layout for a sparsified network only including the most embedded edges. Deleted edges are added back after the layout is calculated.
layout_as_backbone(g, keep = 0.2, backbone = TRUE) layout_igraph_backbone(g, keep = 0.2, backbone = TRUE, circular)
fraction of edges to keep during backbone calculation
logical. Return edge ids of the backbone (Default: TRUE)
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.
