Convert values below a threshold into 1

Question

Let's say if I have the following data

x <- rnorm(100)

I want to create another column where where if x is equal to or greater than 0.2, give it a value of 1 or else 0.

Answer 1

We can create the logical condition and wrap with +

xNew <- +(x >=0.2)

If we need a data.frame,

dat <- data.frame(x, xNew)

Or use ifelse

xNew <- ifelse(x >= 0.2, 1, 0)
