You may like the out-of-the-boxtable remote references:

| 3 |
| 4 |
| 6 |
| 7 |
|   |
|   |
#+TBLFM: $1=remote(raw-data,@@#$3)

The downside is that you need to create an empty table with the right 
size before filling it with C-u C-c *

I get a result. Maybe you used downcase "notasA" where uppercase 
"NotasA" was expected?

#+begin_src R  :var notasA=NotasA
summary(notasA)
#+end_src

#+RESULTS:
| Min.   :3.00 |
| 1st Qu.:3.75 |
| Median :5.00 |
| Mean   :5.00 |
| 3rd Qu.:6.25 |
| Max.   :7.00 |
