ok, some first comments, below. Minor stuff, only.

See my last mail. I think defaulting to CSV (_not_ CVS2!) would be sensible.

Assorted comments:
- Why is the "append" option controlled by the predefined format?
- Uncommenting arguments, that do not apply, is a nifty idea, but does come 
with some drawbacks:
  - Bloats the generated code
  - Seems to suggest that these _could_ be customized for write.csv(2). 
However, the R help says: "append, col.names, sep, dec and qmethod cannot be 
altered." I'd suggest stripping these.
- Remove the "data.frame"-warning (see my last mail).
- For encoding specification, import_spss and import_stata share some code 
(currently in the form of a <snippet>. It might make sense to turn this into 
an embeddable plugin, and use it.

Regards
Thomas
