Actuallu what i need is the cumulative sum of this variable set into one variable. I do not how to do it.(this is my first question).
So what I do is to sum(rrs). This is the result i get

1. |        1 |
2. |        1 |
3. |        2 |
4. |        2 |
5. |        2 |

7. |    11052 |
8. |    12496 |
9. |    12497 |
10. |    12497 |

11. |    12497 |
12. |   264501 |

14. |   265626 |
15. |   286942 |

The second question is that i want to see the value of the last obeservation in the same format as in the previous observation.
