问题描述

我的问题是将每1分钟收集的数据汇总为5分钟平均值。

  DeviceTime Concentration 
6/20/2013 11:13
6/20/2013 11:14
6/20/2013 11:15
6/20/2013 11:16
6/20/2013 11:17
6/20/2013 11:18
6/20/2013 11:19
6/20/2013 11:20
6 / 20/2013 11:21
6/20/2013 11:22
6/20/2013 11:23
6/20/2013 11:24
6/20 / 2013 11:25
6/20/2013 11:26
6/20/2013 11:27
6/20/2013 11:28

...



我想要的结果是:

 设备时间集中
6/20/2013 11:15
6/20/2013 11:20
6 / 20/2013 11:25
6/20/2013 11:30
6/20/2013 11:35
...
/ pre>

5分钟的平均值只是过去五分钟内集中度的简单平均值。

解决方案

使用 dplyr 包,假设你的d ata存储在名为 df 的数据框架中:

  require(dplyr )
df%>%
group_by(DeviceTime = cut(DeviceTime,休息=5分钟))%>%
总结(浓度=平均(浓度))


My question here is to aggregate the data collected at every 1-minute into 5-minute average.

DeviceTime         Concentration
6/20/2013 11:13
6/20/2013 11:14
6/20/2013 11:15
6/20/2013 11:16
6/20/2013 11:17
6/20/2013 11:18
6/20/2013 11:19
6/20/2013 11:20
6/20/2013 11:21
6/20/2013 11:22
6/20/2013 11:23
6/20/2013 11:24
6/20/2013 11:25
6/20/2013 11:26
6/20/2013 11:27
6/20/2013 11:28

...

The result I want is like:

DeviceTime             Concentration
6/20/2013 11:15
6/20/2013 11:20
6/20/2013 11:25
6/20/2013 11:30
6/20/2013 11:35
...

The 5-minute average is just the simple average over the concentration in the past five minutes.

解决方案

Using the dplyr package and assuming, your data is stored in a data frame named df:

require(dplyr)
df %>%
  group_by(DeviceTime = cut(DeviceTime, breaks="5 min")) %>%
  summarize(Concentration = mean(Concentration))
