    ],
    corpora=["before", "after"],
)

Parameters:

Name Type Description Default

freqs

ListOfFreqs

A sequence of token-to-frequency mappings, one per corpus. Each mapping is {token: frequency} for a single corpus

 required

Sequence[str] | None

The names of the corpora, listed in the same order as freqs. If not provided, will default to corpus1, corpus2, etc.
