link2adj function

Extract links from an adjacency matrix

Extract links from an adjacency matrix or an object of calsses "sim" from function bdgraph.sim and "graph" from function graph.sim.

link2adj( link, p = NULL )

Arguments

• link: ($2 \times p$) matrix or a data.frame corresponding to the links from the graph structure.
• p: number of nodes of the graph.

Returns

An adjacency matrix corresponding to a graph structure in which $a_{ij}=1$ if there is a link between notes $i$ and $j$, otherwise $a_{ij}=0$.
