Remember to cover the basics, that is, what you expected to happen 
and
what in fact did happen.  You don't know how to make a good 
report?  See

Your bug report will be posted to the Org mailing list.

I expect =colnames-bug-bad= to parse =test-table= like 
=colnames-bug-good=.  The only difference is the order of :var 
assignments.

**** ECM
#+name: colnames-bug-bad
#+header: :var str="Foo" :var tab=test-table
#+header: :colnames yes
#+BEGIN_SRC R
data.frame(tab)
#+END_SRC

#+RESULTS: colnames-bug-bad
| cell.1 | cell.2 |
|--------+--------|

#+name: colnames-bug-good
#+header: :var tab=test-table :var str="Foo"
#+header: :colnames yes
#+BEGIN_SRC R
data.frame(tab)
#+END_SRC

#+RESULTS: colnames-bug-good
| head.1 | head.2 |
|--------+--------|
| cell.1 | cell.2 |

#+name: test-table
| head.1 | head.2 |
|--------+--------|
| cell.1 | cell.2 |

Let me know if you have questions.

All the best,
Tom

Aloha all,

Answering myself.  This bug is known and was discussed several years 
ago:

 From: Myles English
Subject: Re: [O] babel R: should/does order of parameters matter?
Date: Tue, 29 Mar 2011 16:57:37 +0100

Apparently, ob-R wants tables to be passed to parameters that are early 
in the parameter list.

Also, ob-R expects all the cells in a table to be non-empty.  An empty 
table cell raises Cain.

Argh.

All the best,
Tom
