Rereading your email, still not sure what the question is -- perhaps you
could give a better code example to illustrate the difference between a[[2]]
and mat1 -- but, since you mentioned briefly lists of lists, have you looked
at unlist(, recursive = F)? If applied to a list of lists, it won't unli
I'm not sure I understand your question: a[[2]] is a matrix.
> a <- list(matrix(1:6,2),matrix(5:10,2))
> is.matrix(a[[2]])

x = a[[2]]
> is.matrix(x)
TRUE
