...writing to ask how to manipulate a matrix or dataframe in a specific way. To elaborate, let's consider an example. Assume we have the following 3 by 4 matrix A with elements either 0 or 1, 0 1 1 0 1 0 1 1 0 0 0 1 >From the original matrix A, I'd like to generate a new matrix B satisfing 1) B is initially set to be equal to A, and then 2) Each row of B is a weighted sum of rows of A 3) The weight is given by the number of common 1 shared by the rows. For row 1: it has one common 1 with row 2, thus the weight is 1; it has zero common 1 with row 3, thus the weight is...
