need to look more closely at that and we should try to come up with a
formats for referencing data from source-code in such a way that it
will be as source-code-language independent as possible.
Org tables already have a sophisticated reference system in place
that allows referencing table ranges in other files, as well as
specifying constants in the header arguments of a table. This is
described in [[info:org:References]].

Suppose in some R code, we want to reference data in an org
