tidyEmoji 0.2.0

tidyEmoji is now positioned as a general toolkit for emoji in any text column (social-media posts, reviews, chat logs, survey responses, …), not just tweets.

New features

• emoji_sentiment() scores the emoji in each row using the bundled emoji_sentiment_lexicon (the Emoji Sentiment Ranking of Kralj Novak et al., 2015), returning a mean sentiment in [-1, 1].
• emoji_frequency() returns the count of every emoji in a text column, with name, shortcode and category. top_n_emojis() is now a thin wrapper over it.
• emoji_tokens() expands data to one row per emoji occurrence with its name, category and sentiment score — a tidy, “one-token-per-row” shape.
• emoji_filter() is a clearer, text-agnostic name for emoji_tweets() (which is kept as a synonym).
• New bundled dataset emoji_sentiment_lexicon.

Improvements and fixes

• Grapheme-aware detection. Extraction now keeps skin-tone modifiers and zero-width-joiner sequences intact. Previously a family emoji (👨‍👩‍👧‍👦) was miscounted as four separate people and a skin-tone thumbs-up split into two “emoji”; both are now counted as one.
• Much faster. Detection and counting no longer build a multi-thousand-way regular expression on every call or scan the text once per known emoji; top_n_emojis() in particular is dramatically faster on large inputs.
• top_n_emojis() no longer emits a many-to-many join warning, and reports the emoji’s canonical shortcode (e.g. mask) by default.
• All verbs now return tibbles consistently (emoji_tweets() previously returned a plain data frame), and emoji_extract_unnest() no longer prints a grouping message.
• Bundled emoji data refreshed against the current Unicode emoji list (via data-raw/).

Breaking changes

• Arguments are renamed tweet_tbl -> data and tweet_text -> text. Code that passed these positionally (e.g. df %>% emoji_summary(text_col)) is unaffected; update any calls that named the old arguments.
• top_n_emojis(duplicated_unicode = "yes"/"no") is deprecated in favour of the logical duplicated = TRUE/FALSE. The old argument still works with a warning.
