Frequency of every emoji in a text column

emoji_frequency() counts how often each emoji appears across the whole text column (an entry containing the same emoji twice contributes 2) and returns a tibble sorted by descending count, with each emoji's name, shortcode and category.

Usage

emoji_frequency(data, text)

Arguments

data

A data frame or tibble containing a text column. Grouped data frames are accepted. The verbs that work a row at a time (adding columns, or keeping and expanding rows) carry the grouping through to their result, as dplyr::mutate() and dplyr::filter() do. The verbs that pool across rows – the counts, the co-occurrence edge lists, the time series – warn that they ignore the grouping and return one corpus-wide answer.

text

The text column to scan, supplied unquoted. Any atomic column is accepted and read as character, so a factor works and a numeric, Date or logical one simply contains no emoji. A list column – or a data-frame column – is refused rather than coerced, because coercing one deparses it and the emoji found would be in the code rather than in your data. What counts as an emoji is the same in every verb; see the Detection section of tidyEmoji for the one case that surprises people, code points that are emoji only when they carry U+FE0F.

Value

A tibble with columns emoji, name, shortcode, group and n, sorted by descending n with ties broken by the glyph so the order is deterministic.
