    Check out this package: https://github.com/tidyverse/forcats To convert from labelled for factor you will need the function as_factor package haven.

It may not be the best code, but do the task:

niveis <- data.frame(Antigo = letters[1:10])
a <- data.frame(Niveis = niveis,
              Novo = paste0(rep("NV", 10), rep(1:5,each = 2)))
merge(niveis, a, by = "Antigo", all.x = T)

   Antigo  Novo
        a  NV1
        b  NV1
        c  NV2
        d  NV2
        e  NV3
        f  NV3
        g  NV4
        h  NV4
        i  NV5
        j  NV5

The best code will depend on whether your variable is in a data frame or not
