layout_tbl_graph_centrality | R Documentation |
This layout places nodes in circles with the radii relative to a given centrality measure. Under the hood it use stress majorisation to place nodes optimally given the radius constraint.

graph |
A tbl_graph object |
centrality |
An expression evaluating to a centrality measure for the
nodes. See the different |
scale |
Should the centrality measure be scaled between 0 and 100 |
niter |
number of iterations during stress optimization |
tolerance |
stopping criterion for stress optimization |
tseq |
Transitioning steps |
group |
An expression evaluating to a grouping of the nodes. If given the layout will keep grouped nodes within an angle range of the origin |
shrink |
shrink the reserved angle range for a group to increase the gaps between groups |
circular |
ignored |
A data.frame with the columns x
, y
, circular
, centrality

well as any information stored as node variables in the tbl_graph object.
