I would recommend checking the R documentation. 
 #+begin_src R :colnames t :var t1=TC :results output
  ?quantile
 #+end_src

 #+tblname: TC
 | Data |
 |------|
 |    5 |
 |   10 |
 |   12 |
 |   15 |
 |   20 |
 |   24 |
 |   27 |
 |   30 |
 |   35 |

Consider also the R mailing list r-help@r-project.org. The community is
quite active. 

I believe that you might be looking for the following.

 #+begin_src R :colnames t :var t1=TC 
  quantile(t1$Data,c(1/3,2/3,1))
 #+end_src

 #+RESULTS:
 |  x |
 |----|
 | 14 |
 | 25 |
 | 35 |


HTH,
