Your problem is that you are trying to
use `$` on an atomic vector rather than
a list:
> a<- array(list(NULL),dim=c(2,2))
> a[[1,1]] <- c(a=2,b=3)
> a[[1,1]]$a
Error in a[[1, 1]]$a : $ operator is invalid for atomic vectors
> a[[1,1]]
a b
2 3
> a[[1,1]] <- list(a=2,b=3)
> a[[1,1]]$a
[1] 2
> a[[1,

Dear List,

or,

Hope this will be of some use for you

a<- array(list(NULL),dim=c(2,2))
