Not exactly. Your ECM has one column, and using both columns removes the issue.

Here is another ECM that illustrates the bug:

#+begin_src R :results output :var accounts=(identity '("A B" "C")) 

The bug is in `org-babel-R-assign-elisp' which attempts to get the number of elements in each line of a table, but when the table has just one row or column it gets this wrong.

Actually the length should be 1, i.e. a data.frame with a single column of two elements.

BTW, C-c C-v C-v with point in the src block will show you what R `receives'.

Unfortunately, there are other cases where the variable assignment does not work seamlessly for R src blocks.  There are workarounds, but they are ungainly - like using a src block for another language to render the table and then using a noweb reference to it to import the data.
