1. Please learn how to use dput() to provide examples to responders.
There's not much we can do with a text printout (at least without some work
that I don't care to do).
2. Do you know what mylist[[c(1,2,1)]] means? If not, read ?(Extract) and
note in particular:
"[[ can be applied recursively to lists, so that if the single index i is a
vector of length p, alist[[i]] is equivalent to alist[[i1]]...[[ip]] providing
all but the final indexing results in a list."
As your intent is unclear -- no reproducible example showing the desired
result -- I would suggest just using list indexing to access the matrices
you wish to change. But maybe this does not satisfy your vague request.
Also, something seems screwy in the example you showed: For example, the
[[1]][[2]][[1]] component indicates a 2 x 5 matrix, but I see only 3
columns of text. Am I missing something?
Cheers,
Bert
