将“真"/“假"的数据帧列转换为 1 或 0值并分配给数据框 [英] Convert dataframe column to 1 or 0 for "true"/"false" values and assign to dataframe

问题描述

在 R cli 中，我可以对数据框中的字符列执行以下操作:

In the R cli I am able to do the following on a character column in a data frame:

> data.frame$column.name [data.frame$column.name == "true"] <- 1
> data.frame$column.name [data.frame$column.name == "false"] <- 0
> data.frame$column.name <- as.integer(data.frame$column.name)

我想把它作为一个函数来做，我尝试了下面的代码，输入 data.frame$column.name 作为 arg1.当我返回(arg1)时，我看到它正在工作，但如何将操作返回到原始 data.frame?

I would like to do this as a function and I tried the following code, inputing data.frame$column.name as arg1. I see that it is working when I return(arg1) but how do I return the operation to the original data.frame?

boolean.integer <- function(arg1) {
  arg1 [arg1 == "true"] <- 1
  arg1 [arg1 == "false"] <- 0
  arg1 <- as.integer(arg1)
}

推荐答案

@chappers 解决方案(在评论中)有效 as.integer(as.logical(data.frame$column.name))

@chappers solution (in the comments) works as.integer(as.logical(data.frame$column.name))
