R: creating a new variable based on a boolean variable [duplicate]

Question

I have a boolean variable (e.g. x <- c(T, T, F, T, F,...)) and I want to create a second variable based on my boolean variable. If x == T, then my new variable should take value "A", otherwise, it should take a value of "B". I know it seems easy, but I am new to this.

This is a traditional if...else... question. Please see a guide on r and search for if...else... and you will find many examples and explanations on how to do what you want. — Davy M

To create a variable ybased on the boolean vector xuse:

y <- ifelse(x == T, "A", "B")

The first argument of ifelse is the test, i.e. if x == TRUE, the second argument is what should be done if x == TRUE, the third argument is what should be done if x == FALSE.

Try this

q <- ifelse(x, "A", "B")
