R 一系列数字的比例=>；1.

我试图确定长数据帧上子集的一系列数字的比例。（目的是编写一个函数。）

绿色问题出在序列中

尝试使用R函数

在

之间生成代码（data.table包）

一些例子：

> 0.04:0.4
[1] 0.04
> 0.3 < 0.04:0.4
[1] FALSE
> between(0.3, 0.04, 0.4)
[1] TRUE

> 0.4:4
[1] 0.4 1.4 2.4 3.4
> c(0.3, 0.5) > 0.4:4 #Only use the first value
[1] FALSE FALSE FALSE FALSE
> between(c(0.3, 0.5), 0.4, 4)
[1] FALSE  TRUE

问候

很可能

mean（结果$Value>0.04:0.4）

不是你想要的。我想正确的一行应该是

mean（results$Value>0.04和results$Value谢谢你的两个答案，Nicola，非常感谢。在
之间的“R函数
是什么？”你说的？中间是data.table包的一个函数。是的，谢谢你的链接，我对这个包很熟悉。但是这个链接应该在答案中。谢谢你的建议，Juan，期待将来使用它。
