Details
layout_nicely
tries to choose an appropriate layout function for the
supplied graph, and uses that to generate the layout. The current
implementation works like this:
If the graph has a graph attribute called ‘layout’, then this is used. If this attribute is an R function, then it is called, with the graph and any other extra arguments.
Otherwise, if the graph has vertex attributes called ‘x’ and ‘y’, then these are used as coordinates. If the graph has an additional ‘z’ vertex attribute, that is also used.
Otherwise, if the graph is connected and has less than 1000 vertices, the Fruchterman-Reingold layout is used, by calling
layout_with_fr
.Otherwise the DrL layout is used,
layout_with_drl
is called.
Value
A numeric matrix with two or three columns.
