Dear all,
I now have a sequence of n<-3:21, for each i, I define an array of dimension
array((1/2)^i,c(rep(2,i))), I must update the (i+1)-th array with a loop according to the i-th array, How can I store all the previous arrays (the marginal parts of the (i+1)-th array will not equal to the i-th array)? It is in an iteration from 3 to 21, I later will need all the arrays. If I define 19 different variables, I still can not assign arrays to them in the iteration. What can I do? Thanks.
Regards,
Zhen
Use a list as in:
Alist <- vector(21, mode="list")
n <- 3:21
for(i in n){
Alist[[i]] <- array(1/2^i, rep(2,i))
}with Alist[[3]] as the first non-NULL element, or:
Alist <- lapply(3:21, function(i) array(1/2^i, rep(2,i)))
with Alist[[1]] as the first non-NULL element
