project_to_one_mode: Create a one-mode projection of a two mode graph

Description Usage Arguments Value Examples

View source: R/01_project_to_one_mode.R

Description

Create a one-mode projection of a two mode graph. Converts a rectangular matrix to a square one by taking the cross product of the input matrix. The edge weights in the resulting matrix are equal to the number of transitive ties of each node in the input matrix.

Usage

1
project_to_one_mode(adj_mat, mode = c("rows", "columns"))

Arguments

adj_mat

Sparse matrix of class dgCMatrix

mode

Mode to return. Defaults to projecting by rows.

Value

A double or complex matrix, with appropriate dimnames taken from x and y.

#make matrix
   my_matrix <- sparseMatrix(i = c(1, 1, 2, 3, 4, 4, 5, 6, 7, 7), 
       j = c(1, 2, 3, 4, 5, 6, 7, 8, 9, 10), x = 1
   )
#project to one mode
   project_to_one_mode(adj_mat = my_matrix, mode = "rows")
