i see that it fails until you game the type lattice, but afterward I believe
this functions as designed.
The "R working directory" is not really being used like "working directories"
might usually be considered, it's more just  a hint about where complex data
can be serialized. We used to allow (maybe still do?) you to use load() to get
workspaces from an upstream R actor available downstream, but this is capital-b
Bad.
What I currently see happening with this sample workflow:
-if the R working directories exist, a temporary folder (with timestamp) is
created in that folder and the dataframe is serialized there (to be read by the
downstream R actor using the information it gets on it's input port).
when the Actors are disconnected, the second actor annot find the irisdf object
because it does not share the same workspace (and never will even if the
working dirs were the same).

* I may have completely misunderstood the issue here - in which case please
reopen the bug.
