How can I weight a column with a number, R?

Question

I have a column with anomaly values and I want to weight it with a specific number representing the number of years (32).

How can I do this?

data(mtcars)
mtcars$weight<-apply(mtcars[5], 1, ??, 32)

Is this solving your problem `mtcars[5]*32`? – tmfmnk Feb 01 '20 at 09:59 — tmfmnk, Feb 01 '20 at 09:59

1

mtcars$weighted <- mtcars$drat * 32

Or if your weights are different for each observation

mtcars$weighted <- mtcars$drat * mtcars$cyl

No need for apply, multiplication is already vectorized for your convenience ;)
