I have 150 stops (Cod) and each one of this have a number of service that used.
|        Cod |  SERVICE1 | SERVICE2 | SERVICE3 | Position
------------------------------------------------------
| P05        |     XRS10 |     XRS07|     XRS05| 12455
| R07        |      FR05 |          |          | 4521
| X05        |     XRS07 |     XRS10|          | 57541
I need to put all the services (SERVICE1,SERVICE2,SERVICE3) in one column. That means that I need the following result.
|        Cod |   SERVICE |  Position
------------------------------------------------------
| P05        |     XRS10 |   12455
| P05        |     XRS07 |   12455
| P05        |     XRS05 |   12455
| R07        |      FR05 |    4521
| X05        |     XRS07 |   57541
| X05        |     XRS10 |   57541
There is any way to do this using the sqldf package of R. Or any kind of way to do it?
