#+PROPERTY: session *R*
* Source
#+name: table
| ID | User1 | User2 |
|---------+-------+-------|
| 26/0163 | lrp | nil |
| 37/0001 | nil | nil |
| 37/0003 | nil | nil |
#+begin_src R :var df=table :colnames yes
df
#+end_src
#+results:
| ID | User1 | User2 |
|---------+-------+-------|
| 26/0163 | lrp | nil |
| 37/0001 | nil | nil |
| 37/0003 | nil | nil |
We just checked that the table is correctly imported in R.
* First column (with name)
When I try to get the first column printed along with its name ("ID"), I have
troubles doing so...
#+begin_src R :var df=table :colnames yes
df[, 1]
#+end_src
#+results:
| x |
|---------|
| 26/0163 |
| 37/0001 |
| 37/0003 |
#+begin_src R :var df=table :colnames yes
as.data.frame(df[, 1])
#+end_src
#+results:
| df[, 1] |
|---------|
| 26/0163 |
| 37/0001 |
| 37/0003 |
Here, maybe I'm lacking R knowledge?
* First column (without name)
Now, to get it without the column name:
#+begin_src R :var df=table :colnames no
df[, 1]
#+end_src
#+results:
| ID |
| 26/0163 |
| 37/0001 |
| 37/0003 |
It's not much better, as I don't expect "ID" to be printed here!
Can you clear up things for me? Bad R code? Babel feature?
Best regards,
Seb

Try this:
,----
| #+begin_src R :var df=table :colnames yes
| df[, 1,drop=FALSE]
| #+end_src
|
| #+RESULTS:
| | ID |
| |---------|
| | 26/0163 |
| | 37/0001 |
| | 37/0003 |
`----
Look at
#+BEGIN_SRC R :results output
example(`[.data.frame`)
#+END_SRC
for some help on this.
HTH,
Chuck
