r - Changing binary variables to Yes/No

Question

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

Thanks!

Answer 1

Use ?factor.

See this example

> 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
