嗨我需要计算一些实验的累计昆虫日。这就是我的数据框架

Rep trt      date BLB
1    I   1 7/12/2017   3
2    I   2 7/12/2017   2

6   II   2 7/12/2017   2
7   II   3 7/12/2017   2
8   II   4 7/12/2017   1
9  III   1 7/12/2017   3
10 III   2 7/12/2017   2
11 III   3 7/12/2017   1
12 III   4 7/12/2017   1
13  IV   1 7/12/2017   0
14  IV   2 7/12/2017   3
15  IV   3 7/12/2017   3
16  IV   4 7/12/2017   0
17   I   1 7/20/2017  12
18   I   2 7/20/2017   6
19   I   3 7/20/2017   7

23  II   3 7/20/2017  25
24  II   4 7/20/2017  17
25 III   1 7/20/2017  18
26 III   2 7/20/2017   6
27 III   3 7/20/2017  48

33   I   1 7/27/2017   1
34   I   2 7/27/2017   3

36   I   4 7/27/2017   0
37  II   1 7/27/2017   1
38  II   2 7/27/2017   0
39  II   3 7/27/2017   1
40  II   4 7/27/2017   0
41 III   1 7/27/2017   1

46  IV   2 7/27/2017   0
47  IV   3 7/27/2017   1
48  IV   4 7/27/2017   2
49   I   1  8/2/2017   0
50   I   2  8/2/2017   0
51   I   3  8/2/2017   1
52   I   4  8/2/2017   0
53  II   1  8/2/2017   0
54  II   2  8/2/2017   0
55  II   3  8/2/2017   0
56  II   4  8/2/2017   0
57 III   1  8/2/2017   1
58 III   2  8/2/2017   0
59 III   3  8/2/2017   0
60 III   4  8/2/2017   0
61  IV   1  8/2/2017   0
62  IV   2  8/2/2017   0
63  IV   3  8/2/2017   0
64  IV   4  8/2/2017   2

结构将是：

    data.frame':    64 obs. of  4 variables:
 $ Rep : Factor w/ 4 levels "I","II","III",..: 1 1 1 1 2 2 2 2 3 3 ...
 $ trt : Factor w/ 4 levels "1","2","3","4": 1 2 3 4 1 2 3 4 1 2 ...
 $ date: Factor w/ 4 levels "7/12/2017","7/20/2017",..: 1 1 1 1 1 1 1 1 1 1 ...
 $ BLB : int  3 2 4 0 1 2 2 1 3 2 ...

要做到这一点，我需要计算不同治疗的每个日期组合的昆虫的平均值。例如，我必须计算每次治疗的日期7/12和7/20之间的每一次。然后我需要计算日期7/20和7/27等之间的平均值。有谁知道如何使用r软件这样做？我真的很感激帮助!!

Answer 1

首先创建数据（如果你提供了dput（数据）......会很好）：

 <input id="firstName" type="text" class="form-control" name="Patient[firstName]" value="{{ $user->getFirstName() }}" required autofocus placeholder="First Name">
 <input id="mobileArea" type="text" class="form-control" name="Patient[mobileArea]" value="{{ $user->mobileArea() }}" required autofocus placeholder="mobileArea"

简单的子集和聚合：

protected function validationRules()
{
    return [
        'Patient.firstName' => 'required|string|min:2',
        'Patient.lastName'        => 'required|string',
        'Patient.sex'        => 'required|string',
        'Patient.city'        => 'required|string',
        'Patient.states'        => 'required|string',
        'Patient.address1'        => 'required|string|min:2',
        'Patient.zip'        => 'required|string|min:2',
        'Patient.mobileArea'        => 'string|min:3|required_with:Patient.mobilePhone',
        'Patient.mobilePhone'        => 'string|min:7|required_with:Patient.mobileArea',
        'Patient.homePhone'        => 'string|min:7|required_with:Patient.homeArea',
        'Patient.homeArea'        => 'string|min:3|required_with:Patient.homePhone',
    ];
}

Answer 2

您错过了某个日期组合小组@useR

有（2017-07-12,2017-07-27），（2017-07-12,2017-08-02），（2017-07-20,2017-08-02）也。

如何用r计算累积昆虫日？
