Lisa -
Are you looking for this?
x <- list(list(matrix(sample(c(0,1), 4, replace = T), 2),
+ matrix(sample(c(2,3), 4, replace = T), 2)),
+ list(matrix(sample(c(0,1), 6, replace = T), 2), matrix(sample(c(2,3), 6,
+ replace = T), 2)))
unlist(x,recursive=FALSE)
[[1]]
[,1] [,2]
[1,] 0 0
[2,] 1 0
[[2]]
[,1] [,2]
[1,] 3 2
[2,] 3 2
[[3]]
[,1] [,2] [,3]
[1,] 1 0 1
[2,] 0 1 0
[[4]]
[,1] [,2] [,3]
[1,] 2 2 2
[2,] 2 2 3

Dear all,
I just want to arrange a multi-level list to a one-level list. For example:
x <- list(list(matrix(sample(c(0,1), 4, replace = T), 2),
matrix(sample(c(2,3), 4, replace = T), 2)),
list(matrix(sample(c(0,1), 6, replace = T), 2), matrix(sample(c(2,3), 6,
replace = T), 2)))
x
[[1]]
[[1]][[1]]
[,1] [,2]
[1,] 1 1
[2,] 0 0
[[1]][[2]]
[,1] [,2]
[1,] 3 2
[2,] 3 3
[[2]]
[[2]][[1]]
[,1] [,2] [,3]
[1,] 1 0 0
[2,] 0 1 0
[[2]][[2]]
[,1] [,2] [,3]
[1,] 2 3 3
[2,] 3 3 3
If I do this work one time, I will arrange it like this:
c(x[[1]], x[[2]]) # Only consider the first level of the list.
[[1]]
[,1] [,2]
[1,] 1 1
[2,] 0 0
[[2]]
[,1] [,2]
[1,] 3 2
[2,] 3 3
[[3]]
[,1] [,2] [,3]
[1,] 1 0 0
[2,] 0 1 0
[[4]]
[,1] [,2] [,3]
[1,] 2 3 3
[2,] 3 3 3
But when I repeat this work many times and the levels will change each time
in a loop, how can I pass the arguments to c()? For example, in the first
iteration, the first level of a list is 3, in the second iteration, the
first level of a list is 5? ….
Any help would be greatly appreciated.
Lisa
