...ot R (for example "bloc notes" of Windows). The problem is that the matrix is not in the explicit form as 0 1 1 1 0 0 1 0 0 but it is a scattered matrix where in each row there are two nodes that have a direct path. The matrix is a b a c b a c a For example, the first row exspress that node a and node b are connected by a direct line. Can R transform this matrix in the first matrix that I wrote ? Are there any struments? 2: Which is the max dimension of a matrix that R can use (1000X1000?, 500000X500000?)? What is the biggest dimension of a file that R can import? Thank yo...
