Re: [O] was this intentional with the default header ":results value"

[Thomas S. Dye]

Or, fiddling a bit more.

#+name: luo
#+BEGIN_SRC R :results output raw
  library(ascii)
  df <- data.frame(c1="123456789123456789000",c2=2)
  df$c1 <- as.vector(df$c1)
  print(ascii(df,digits=c(0,0),include.rownames=F),type="org")
#+END_SRC

#+RESULTS: luo
|                    c1 | c2 |
|-----------------------+----|
| 123456789123456789000 |  2 |
