I have this table x and y like this
| x | y | 
|---|---|
| 0.6 | 0.2 | 
| 0.8 | 0.2 | 
| 0.2 | 0.2 | 
| 0.4 | 0.2 | 
| 0.6 | 0.4 | 
| 0.8 | 0.4 | 
| 0.2 | 0.4 | 
| 0.4 | 0.4 | 
| 0.6 | 0.8 | 
| 0.8 | 0.8 | 
| 0.2 | 0.8 | 
| 0.4 | 0.8 | 
| 0.6 | 0.6 | 
| 0.8 | 0.6 | 
| 0.2 | 0.6 | 
| 0.4 | 0.6 | 
- The question is how to order the table using r to be like below?
| x | y | 
|---|---|
| 0.2 | 0.2 | 
| 0.2 | 0.4 | 
| 0.4 | 0.2 | 
| 0.4 | 0.4 | 
| 0.4 | 0.6 | 
| 0.6 | 0.4 | 
| 0.6 | 0.6 | 
| 0.6 | 0.8 | 
| 0.8 | 0.6 | 
| 0.8 | 0.8 | 
if somebody knows please,
- I tried to use the command order but it just order in two ways increasing and decreasing.
