-#' Create Object Dependencies Structure Within Parsed Code
-#'
-#' @description This function constructs a dependency structure that identifies the relationships between objects in
-#' parsed code. It helps you understand which objects are needed to recreate a specific object.
-#'
-#' @details This function assumes that object relationships are established using the `<-`, `=`, or `->` assignment
-#' operators. It does not support other object creation methods like `assign` or `<<-`, nor non-standard-evaluation
-#' methods. To specify relationships between side-effects and objects, you can use the comment tag
-#' `# @linksto object_name` at the end of a line where the side-effect occurs.
-#'
-#' @param code An `expression` with `srcref` attribute or a `character` with the code.
-#' @param object_names (`character(n)`) A vector containing the names of existing objects.
-#'
-#' @return A `list` with three components:
-#' - `occurrence`: A named `list` where object names are the names of existing objects, and each element is a numeric
-#' vector indicating the calls in which the object appears.
-#' - `cooccurrence`: A `list` of the same length as the number of calls in `parsed_code`
-#' (`parsed_code = parse(text = code)` for code input as `character` and `parsed_code = code` for expression input.
-#' It contains `NULL` values if there is no co-occurrence between objects or a `character` vector indicating the
-#' co-occurrence of objects in a specific `parsed_code` call element. If it's a character vector, the first element is
-#' the name of the dependent object, and the rest are the influencing objects.
-#' - `effects`: A named `list` where object names are the names of existing objects, and each element is a numeric
-#' vector indicating which calls have an effect on that object. If there are no side-effects pointing at an object,
-#' the element is `NULL`.
