Ah - makes sense. Haven't looked at that yet. Should be possible. If it
doesn't work I'll come back to you on Monday.

Ok - if it is just the case of not indenting in the source block, then it
is not necessary to change it.

Thanks - that's brilliant.

That is an option. I'll change it accordingly.

tangle-add-vars should be perfect. This could be a list of variables with
their values and also modes (read-only, auto-revert comes to mind). One
could split it though in two, I.e. an additional tangle-mode for modes, but
one tangle-add-vars should be fine.
Thanks a lot for all this, as it makes the integration of org, ESA and R
much better. I'll see that I write up some how to for package development
from org based on this.
Cheers and have a nice weekend,
