将二进制变量更改为是/否 [英] Changing binary variables to Yes/No

问题描述

所以我有一个要分析的数据框.问题在于，数据帧中有一堆1和0(不是，是1)是(是，0是否).如何修改数据框以使其为1和0，而不是1和0，所以我可以使用逻辑回归?我敢肯定有一个简单的解决方法，我没有想到

So I have a data frame that I'd like to analyze. The problem is that instead of Yes/No, there are a bunch of 1s and 0s (1 being Yes, 0 being No) in the data frame. How do I modify the data frame to make it so instead of the 1s and 0s there are Yes and No so I can use logistic regression? I am sure there is a simple fix for this that I am not thinking of

谢谢！

推荐答案

使用?factor.

查看此示例

> set.seed(1)
> dummyVariable <- sample(c(0,1), 10, TRUE)  # bunch of 0 and 1
> newVariable <- factor(dummyVariable, levels=c(0,1), labels=c("No", "Yes"))
> newVariable  # this is now a dummy variable ready for regression analysis
 [1] No  No  Yes Yes No  Yes Yes Yes Yes No 
Levels: No Yes
