R:使用因子变量删除逻辑变量中的数据

I made the following example code to give you an idea of my real dataset. I have 2 datasets, a factor variable List and a logical variable ok.

我做了下面的示例代码，让您了解我的真实数据集。我有两个数据集，一个因子变量列表和一个逻辑变量。

df1 <- c("a","b","c","d","e","f","g")
df2 <- c("a","d","e")
List <- factor(as.integer(df1 %in% df2))
ok <- c(TRUE,FALSE, FALSE,FALSE,TRUE,FALSE,TRUE)

The List and the ok variables has both a length of 7. I want to remove all the samples in List with the condition TRUE in ok. For example: the first, fifth and seventh variables need to be removed in the List variable.

列表和ok变量的长度都是7。我想把列表中的所有样本都去掉，条件在ok中为真。例如:第一个、第五个和第七个变量需要在列表变量中删除。

Can anyone help me with this?

有人能帮我一下吗?

Thanks

谢谢

2 个解决方案

#1

Easier than you think.

比你想象的容易。

List[!ok]

#2

Perhaps List[!ok]? BTW, you don't need as.logical as vector ok will be saved internaly as logical.

也许列表(!好)?顺便说一句，你不需要as。逻辑作为向量ok将作为逻辑保存在内部。
