I have this list:
a <- list()
a[[1]] <- matrix(c(1,2),nrow = 2)
How do I select element 2 ?

To access the matrix element 2 in the list first you have to access the matrix -- a[[1]] because it is the first element of the list -- and then access the second element of the matrix -- a[[1]]][[2]] or a[[1]][2].
a[[1]][[2]]
[1] 2
