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.
adjacencyMatrix(object)

Thus far only implemented for graphBAM objects.
adjacencyMatrix returns an n x n matrix, where n is
the number of nodes in the graph, ordered in the same manner as
seen in the nodes method. All cells in the matrix are 0
except 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, stringsAsFactors = TRUE)
g1 <- graphBAM(df, edgemode = "directed")
