Convert a numeric matrix generated with make_adjacency into a binary matrix

This function takes an adjacency matrix generated with make_adjacency as input and converts it to a binary matrix using a binarization threshold.

Usage

make_binary(adj, threshold, output_plot = FALSE)

Arguments

adj

an adjacency matrix converted from a raw input matrix via make_adjacency.

threshold

a numeric value that is within the range min(adj) < threshold <= max(adj) of the input which is then used for binarisation.

# look at raw matrix

#> [1,]    0   -1    2
#> [2,]    1    2    4
#> [3,]    4    0    0
# convert raw matrix into a edgynode adjacency matrix
edgynode_matrix <- edgynode::make_adjacency(edgynode::adjacency_matrix_test_3)
# convert into a binary matrix
edgynode_matrix_binary <- edgynode::make_binary(edgynode_matrix, threshold = 1)
