[O] ob-R, about :results value verbatim drawer

[Feng Shu]

When I run follow code, it just work:

       #+begin_comment
       
       #+BEGIN_SRC R :results value verbatim drawer
       data <- list(a="[[./test1.org]]",b="[[./test2.org]]",c="[[./test3.org]]")
       c(data$a,data$b,data$c)
       #+END_SRC
       
       #+RESULTS:
       :RESULTS:
       [[./test1.org]]
       [[./test2.org]]
       [[./test3.org]]
       :END:
       


but when I add a #+PROPERTY, it show error like below, how to deal with
it ?  thanks ...

      #+PROPERTY: header-args:R :colnames yes :rownames no :exports both
      #+BEGIN_SRC R :results value verbatim drawer
      data <- list(a="[[./test1.org]]",b="[[./test2.org]]",c="[[./test3.org]]")
      c(data$a,data$b,data$c)
      #+END_SRC
