Compute an Adjacency Matrix for a graphBAM object
Though unwieldy for large matrices, a full adjacency matrix can be useful for debugging and export.
If the graph is undirected then recicprocal edges are explicit in the matrix.
Thus far only implemented for
adjacencyMatrixreturns an n x n matrix, where n is the number of nodes in the graph, ordered in the same manner as seen in the
nodesmethod. All cells in the matrix are
0except where edges are found.
from <- c("a", "a", "a", "x", "x", "c") to <- c("b", "c", "x", "y", "c", "a") weight <- c(3.4, 2.6, 1.7, 5.3, 1.6, 7.9) df <- data.frame(from, to, weight) g1 <- graphBAM(df, edgemode = "directed") adjacencyMatrix(g1)
Looks like there are no examples yet.
