AFAICT :tangle takes only "yes", "no", or a literal pathname.
Stuff like
:tangle (my-lisp-function arg1 arg2)
will work.
How
might I dynamically generate a pathname for :tangle? I suppose what I
want is some kind of escape syntax for eval'ing a Lisp form, like
maybe:
:tangle %(my-dynamic-filename-generator)
Try this:
#+BEGIN_SRC R :tangle (concat "my-" "file" ".R")
abs <- def
#+END_SRC
just as an example.
BTW, org-babel-view-src-block-info (C-c C-v C-i) will show you what header
args evaluate as without the need to eval or tangle them.
