R: Remove -Inf and Inf from a vector

Question

I can remove na values from a vector:

na.omit(c(1,2,NA,3))

But how can I remove Inf and -Inf?

na.omit(c(1,2,NA,3,Inf))
na.omit(c(1,2,NA,3,-Inf))

See `is.finite` and `is.infinite`. – joran Jun 28 '19 at 21:49 — joran, Jun 28 '19 at 21:49

Remember that is.na and is.infinite may operate on vectors, returning vectors of booleans. So you can filter the vector as so:

> x <- c(1, 2, NA, Inf, -Inf)
> x[!is.na(x) & !is.infinite(x)]
[1] 1 2

If this needs to be done inline, consider putting the above in a function.
