------- Comment #3 from soong at nceas.ucsb.edu  2009-04-28 11:56 -------
I was under the impression the R working directory (Rwd) was a parameter to set
the working directory of the R actor, for whatever reason the user might
desire.  I thought it was a redundant convenience feature just like the --save
parameter, as the user could certainly change working directories in the actor,
just as the user could save.image().

It's not clear to me (in the abstract -- I get the technical reasons) why
Kepler's ability to pass data between actors should be dependent on the
parameterization of those actors.

All in all, it seems like Kepler already has a place to store temporary stuff
(.kepler), R is perfectly capable of accepting full paths to files, workflow
execution is not dependent on the user correctly parameterizing the Rwd, and
the user is free to muck with the working directory in R (which I just realized
will also break workflows).

>From the previous comment, it sounds like the actor functions as designed, so I
presume there are other reasons I'm not aware of for having this type of
working directory that outweigh the above considerations.  I'm leaving as
resolved.
