sparsematrix_from_matrix function

Convert matrix to sparse matrix

Converts adjacency matrices (class "matrix") to a sparse matrices (class "dgCMatrix").

sparsematrix_from_matrix(adj_mat)

Arguments

• adj_mat: Adjacency matrix.

Returns

A sparse matrix of class dgCMatrix.

Examples

#make matrix
   my_matrix <- rep(0, 100)
   my_matrix[c(1, 11, 22, 33, 44, 54, 65, 76, 87, 97)] <- 1
   my_matrix <- matrix(data = my_matrix, nrow = 10, ncol = 10)
#convert to sparsematrix
   sparsematrix_from_matrix(adj_mat = my_matrix)
