working with sparse matrix
Hi, I have a 500x 53380 sparse matrix and I am trying to dichotomize it. Under sna package I have found event2dichot yet it doesnt recognize sparse matrix and requires adjacency matrix or array. I tried to run a simple loop code for (i in 1:500) for (j in 1:53380) if (matrix[i,j]>0) matrix[i,j]=1 yet this takes a lot of time to run, I mean it has been last two hours and it is stil running. I am wondering...
