This function computes a pMDS layout using the RSpectra package for efficient
eigen decomposition.
Usage
fast_pmds(g, pivots, weights = NA, dim = 3)
Arguments
- g
An igraph or a tbl_graph object
- pivots
Number of pivots to use for distance calculations
- weights
Optional edge weights to use for distance calculations
- dim
Desired number of dimensions for the layout
Value
A matrix of coordinates for the pMDS layout
