Hello R-helpers, I have the following code that works well, b <-list() for (i in 1:3){ a <- matrix(runif(1),3,3) b[[i]] <- a } b
however, I need to do something similar with two loops and I was looking for something that would look like b <- list() for (i in 1:3){ for (j in 1:4){ a <- matrix(runif(1),3,3) b[[i,j]] <- a #but this doesn´t work } } Anyway, I wanted "b" to loop like [[i=1, j=1]] [[i=1, j=2]] (...) a[i=1, j=1] a[i=1,j=2] (...) [[i = 2, j=1]] (...) a[i = 2, j = 1] (...) (...) Can anybody help me?
