[R] structure vs. matrix

[Gabor Grothendieck]

In general, you want to use as high level a construct as possible
since then the details implementing the construct can be modified
and improved without your code changing.  This is really just an
aspect of modularity.  Thus matrix would be preferred.

Actually since R allows access to the lower level details this type of
benefit is not really guaranteed but as a matter of principle I
would use other constructs than structure whenever possible.
