[R] List to Array

[Werner Wernersen]

Oh yes, I should give an example:

m <- matrix(1:6,nrow=3)
L <- list(m,m)

Output of L:
[[1]]
     [,1] [,2]
[1,]    1    4
[2,]    2    5
[3,]    3    6

[[2]]
     [,1] [,2]
[1,]    1    4
[2,]    2    5
[3,]    3    6


I would like to transform L to and array looking like
this:
, , 1

     [,1] [,2]
[1,]    1    4
[2,]    2    5
[3,]    3    6

, , 2

     [,1] [,2]
[1,]    1    4
[2,]    2    5
[3,]    3    6
