I don't think this is a bug as it is not clear what should happen.
In the org manual it states concerning the :results file

,----
|    * `file' The results will be interpreted as the path to a file, and
|      will be inserted into the Org mode buffer as a file link.  E.g.,
|      `:results value file'. 
`----

But the :colnames only works on tables (i.e. :results table) - but the
result is represented as a link to a file. So what should happen?

If you would like to have a table with links to files, the easiest is to
put the file names into [[]] in R and then return them in a table - or
use :results output and "draw" the table.

But as it stands, these two header arguments do not go together.

It would be nice to have a warning (or even error) in org, or at least a
table of header argument precedence.

By the way - never used the :results file - but now I will! Thanks.

Hope this helps,

Rainer
