[R] list of list

[jim holtman]

Is this what you mean:

ASL <- list()
for (j in 1:5){
    RES <- list()
    for (i in 1:5) RES[[i]] <- i ^ j  # create list
    ASL[[j]] <- RES  # store 'list of list'
}

What is the problem that you are trying to solve?
Tell me what you want to do, not how you want to do it.
