How to avoid warning when introducing NAs by coercion?

Question

I generally prefer to code R so that I don't get warnings, but I don't know how to avoid getting a warning when using `as.numeric` to convert a character vector.For example: x <- as.numeric(c("1", "2", "X"))Will give me a warning because it introduced NAs by coercion. I want NAs introduced by coercion - is there a way to tell it "yes this is what I want to do". Or should I just live with the warning?Or should I be using a different function for this task?

Answer 1

x <- suppressWarnings(as.numeric(c("1", "2", "X")))
