How can repeat this process for an unknown number of entries in the list? In
other words, how
You get the number of list elements with length(D),
the dimensions of M1 with dim(M1)
see help with:
?dim
?length
Hope this helps...

If they are already a matrix in the list, then you don't have to use
'as.matrix'; you can just say:
M1 - D[[1]]
Now the question is, what do you mean by how do you index M1? Do you
want to go through the list applying a function to each matrix? If
so, then just 'lapply'. For example, to get
