List bundled emoji lexicons

Source: R/emoji-lexicon-api.R
emoji_lexicons.Rd

emoji_lexicons() returns a tibble describing the lexicons bundled with tidyEmoji and any user-registered ones: their name, type (sentiment or emotion), dimensions, number of emoji, source and licence.

Usage

emoji_lexicons()

Value

A tibble with columns name, type, dimensions, n, source, licence.

n is the lexicon's row count. For the two bundled ones that is also the number of emoji they score, 969 and 150, because each has one row per code-point key. A registered lexicon need not: two spellings of one emoji are two rows and score one glyph, and a row whose glyph yields no key at all (an empty string, an NA) is counted here and matched never. length(unique(emoji_key(tbl$emoji))) is the count of distinct emoji, the same distinction emoji_provenance() draws for n_emoji.
