Details

• tweet_info(): <tbl_df> with columns for all the following fields, as well as a column tweet giving the original text. Note that this function is called internally by all of the following, so it may be more efficient to store this result and extract columns as needed.

• tweet_permillage(): <numeric> indicating the number of characters used as a proportion of the maximum number of characters allowed. I.e. this will be > 0 and <= 1 for valid tweets.

• tweet_weighted_length(): <integer> indicating the 'length' of the tweet according to Twitter's parsing rules. The maximum allowed length is 280 characters.

• tweet_is_valid(): <logical> indicating whether or not the tweet is valid according to Twitter's parsing rules

• tweet_valid_range_start()/tweet_valid_range_end(): <integer> indicating the index of the first/last characters of the valid range of a tweet

• tweet_display_range_start()/tweet_display_range_end(): <integer> indicating the index of the first/last characters of the display range of a tweet
