我使用像这样的data.frame：
Country Date balance_of_payment business_confidence_indicator consumer_confidence_indicator CPI Crisis_IMF
1 Australia 1980-01-01 -0.87 100.215 99.780 25.4 0
2 Australia 1980-04-01 -1.62 100.061 99.746 26.2 0
3 Australia 1980-07-01 -3.70 100.599 100.049 26.6 0
4 Australia 1980-10-01 -3.13 100.597 100.735 27.2 0
5 Australia 1981-01-01 -2.73 101.149 101.016 27.8 0
6 Australia 1981-04-01 -4.11 100.936 100.150 28.4 0
我想在describe(dataset)包中使用Hmisc创建摘要统计信息。
我需要区分Crisis_IMF 1之前的四分之一时间段，Crisis_IMF为1的时间以及Crisis_IMF之后的状态n-quaters 1。
要选择Crisis_IMF为1的时间，我做了describe(dataset[dataset$Crisis_IMF==1,"balance_of_payment"])。
但我不知道如何在事件发生后的n个季度（例如8个）的时间跨度内发出命令。

dataset$Crisis_IMF

一个国家可能会有一个以上的危机时期。那就是来自澳大利亚的危机来自1990-01-01 to 1991-04-01 and 2002-01-01 to 2005-01-01。我想创建3个不同的describe命令，这些命令显示变量在上述状态中的行为。
答案 0 :(得分：3)
您还没有提供完整的数据，因此我必须猜测您的Crisis_IMF列有一个完整的零序列（在危机前），然后是一个完整的序列（在此期间国际货币基金组织的危机被认为是有效的，最后是一连串的零（危机后）。
下面我已经合成了我自己的测试数据。我只合成了列Crisis_IMF和balance_of_payment，因为这些列似乎是与您的问题相关的唯一列。我使用了30行，前10个，前10个，危机后的最后10个。我对balance_of_payment使用了一种随机抛物线弧，但这完全是随机的。

该解决方案的工作原理是首先计算危机生效期间的索引范围crisisRange。然后它向data.frame附加一个新列Off_Crisis，它使用前面的负数和后面的正数来捕获偏离该行危机的四分之一，并假设每行恰好代表四分之一。< / p>
然后可以通过describe()列上的子集进行Off_Crisis次调用，只获得与每次通话所需的危机相对应的季度。

对于这个演示，我综合了五个时期：10行非危机，10行危机（第一行），20行非危机，10行危机（第二行）和10行非危机。算法是相同的，即计算Off_Crisis列（这次更加困难！）然后使用它来为每个describe()调用的data.frame进行子集化。只有现在，来自不同危机的数据点才会合并到子集中。
