 Several other variables can be derived from the raw data with the
 following functions:
 
--   `add_duration()` adds a variable called `duration` based on the
-    sequence of timestamps. The basic logic is that the duration of a
-    visit is set to the time difference to the subsequent visit, unless
-    this difference exceeds a certain value (defined by argument
-    `cutoff`), in which case the duration will be replaced by `NA` or
-    some user-defined value (defined by `replace_by`).
--   `add_session()` adds a variable called `session`, which groups
-    subsequent visits into a session until the difference to the next
-    visit exceeds a certain value (defined by `cutoff`).
--   `extract_host()`, `extract_domain()`, `extract_path()` extracts the
-    host, domain and path of the raw URL and adds variables named
-    accordingly. See function descriptions for definitions of these
-    terms. `drop_query()` lets you drop the query and fragment
-    components of the raw URL.
--   `add_next_visit()` and `add_previous_visit()` adds the previous or
-    the next URL, domain, or host (defined by `level`) as a new
-    variable.
--   `add_referral()` adds a new variable indicating whether a visit was
-    referred by a social media platform. Follows the logic of Schmidt et
-    al., [(2023)](https://doi.org/10.31235/osf.io/cks68).
--   `add_title()` downloads the title of a website (the text within the
-    `<title>` tag of a web site’s `<head>`) and adds it as a new
-    variable.
--   `add_panelist_data()`. Joins a data set containing information about

 ## Classification
 
--   `classify_visits()` categorizes website visits by either extracting
-    the URL’s domain or host and matching them to a list of domains or
-    hosts, or by matching a list of regular expressions against the
-    visit URL.

 ## Summarizing and aggregating
 
--   `deduplicate()` flags or drops (as defined by argument `method`)
-    consecutive visits to the same URL within a user-defined time frame
-    (as set by argument `within`). Alternatively to dropping or flagging
-    visits, the function aggregates the durations of such duplicate
-    visits.
--   `sum_visits()` and `sum_durations()` aggregate the number or the
-    durations of visits, by participant and by a time period (as set by
-    argument `timeframe`). Optionally, the function aggregates the
-    number / duration of visits to a certain class of visits.
--   `sum_activity()` counts the number of active time periods (defined
-    by `timeframe`) by participant.
