我有一個很大的數據集,類似於下面的可重現樣本數據。在R中彙總每週水平數據到每週水平
Interval value
1 2012-06-10 552
2 2012-06-11 4850
3 2012-06-12 4642
4 2012-06-13 4132
5 2012-06-14 4190
6 2012-06-15 4186
7 2012-06-16 1139
8 2012-06-17 490
9 2012-06-18 5156
10 2012-06-19 4430
11 2012-06-20 4447
12 2012-06-21 4256
13 2012-06-22 3856
14 2012-06-23 1163
15 2012-06-24 564
16 2012-06-25 4866
17 2012-06-26 4421
18 2012-06-27 4206
19 2012-06-28 4272
20 2012-06-29 3993
21 2012-06-30 1211
22 2012-07-01 698
23 2012-07-02 5770
24 2012-07-03 5103
25 2012-07-04 775
26 2012-07-05 5140
27 2012-07-06 4868
28 2012-07-07 1225
29 2012-07-08 671
30 2012-07-09 5726
31 2012-07-10 5176
我想這彙總數據每週水平得到類似以下的輸出:
Interval value
1 Week 2, June 2012 *aggregate value for day 10 to day 14 of June 2012*
2 Week 3, June 2012 *aggregate value for day 15 to day 21 of June 2012*
3 Week 4, June 2012 *aggregate value for day 22 to day 28 of June 2012*
4 Week 5, June 2012 *aggregate value for day 29 to day 30 of June 2012*
5 Week 1, July 2012 *aggregate value for day 1 to day 7 of July 2012*
6 Week 2, July 2012 *aggregate value for day 8 to day 10 of July 2012*
如何做到這一點很容易,而無需編寫長碼?
您使用的[XTS]標籤,但它並不像你有一個XTS對象。你說得對,雖然xts可能是最簡單的方法。你有搜索嗎?看看'to.weekly','apply.weekly','period.apply'和搜索SO。 – GSee
