Sparse Matrices in R
I have data in i,j,r format,
where r is the value in location A[i,j] for some imaginary matrix A.
I need to build this matrix A, but given the sizes of i and j, I believe that using a sparse format would be most adequate.
Hopefully this will allow me to perform some basic matrix manipulation such as multiplication, addition, rowsums, transpositions, subsetting etc etc.
Is there any way
