layout_tbl_graph_pmds | R Documentation |
This layout is similar to the 'mds' layout but uses only a subset of pivot nodes for the mds calculation, making it considerably faster and thus suited for large graphs
layout_tbl_graph_pmds(graph, pivots, weights = NULL, circular = FALSE)
graph |
A tbl_graph object |
pivots |
The number of pivot nodes |
weights |
An expression evaluated on the edge data to provide edge weights for the layout. Currently ignored for the sparse version |
circular |
ignored |
A data.frame with the columns x
, y
, circular
as
well as any information stored as node variables in the tbl_graph object.
The underlying algorithm is implemented in the graphlayouts package by David Schoch
