Dear R users,
The solution is probably simple but I need someone to point me to it.
How can I to generate a matrix from a numeric sequence of 1:10 like 'A' or 'B'
below:
A)
|--------------------|
| 1 2 3 4 5 |
|--------------------|
| 1 | 0 |
| 2 | 1 0 |
| 3 | 2 5 0 |
| 4 | 3 6 8 0 |
| 5 | 4 7 9 10 0 |
|--------------------|
B)
|--------------------|
| 1 2 3 4 5 |
|--------------------|
| 1 | 0 1 2 3 4 |
| 2 | 1 0 5 6 7 |
| 3 | 2 5 0 8 9 |
| 4 | 3 6 8 0 10 |
| 5 | 4 7 9 10 0 |
|--------------------|
This question is related with the possible combinations of five objects two the
two, i.e, C(5,2).
Any help would be greatly appreciated.
Regards,
