create_sparse_matrix: Create Sparse Matrix

In clustur: Clustering

Create Sparse Matrix

Description

Given a list of i indexes, j indexes, and distances values, we can create a sparse distance matrix for you. Each vector must have the same size.

Usage

create_sparse_matrix(i_index, j_index, distances)

Arguments

i_index	A list of i indexes, must be numeric
j_index	A list of j indexes, must be numeric
distances	A list of the distance at the i and j index

Value

a 'dgTMatrix' from the 'Matrix' library.

Examples

 i_values <- as.integer(1:100)
 j_values <- as.integer(sample(1:100, 100, TRUE))
 x_values <- as.numeric(runif(100, 0, 1))
 s_matrix <- create_sparse_matrix(i_values, j_values, x_values)
