layout_tbl_graph_focus.RdThis layout constrains node placement to a radius relative to its distance to a given node. It then uses stress majorisation to find an optimal node distribution according to this constraint.

)a tbl_graph object
An expression evaluating to a selected node. Can either be a
single integer or a logical vector with a single TRUE element.
An expression evaluated on the edge data to provide edge weights for the layout. Currently ignored for the sparse version
number of iterations during stress optimization
stopping criterion for stress optimization
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 the reserved angle range for a group to increase the gaps between groups
ignored
A data.frame with the columns x, y, circular, distance as
well as any information stored as node variables in the tbl_graph object.
