Hello there,

I am struggling with something that is perhaps very simple.

Consider this factor :

```
> factor(c('a','b','c','d','a','b'))
[1] a b c d a b
Levels: a b c d
```

This factor is already sorted by order of importance.

That is `a`

is better than `b`

, and so on. I would like to keep the first 2 top levels, and put the rest in some `other`

category. Very much like `fct_lump`

but here the lumping has nothing to do with the frequency (they all appear once).

Can I do that with `forcats`

?

Thanks!
