A data analyst working in R Markdown runs code to analyze the data and create visualizations. The analyst sets up a practice report for stakeholders. What should the analyst add to the file while making edits to ensure that stakeholders understand what has changed?

While visualizations are important for presenting data insights, they do not directly inform stakeholders about the changes made in the code itself. Visualizations illustrate results but do not explain the underlying modifications or the reasons for those adjustments, which is crucial for effective communication.

Warnings are typically used to indicate potential issues or errors in the code execution, rather than to communicate changes made during edits. While they serve a function in alerting users to problems, they do not provide explanatory context about the analyst's edits, making them less suitable for stakeholder understanding.

Delimiters are used to separate data or code elements but do not contribute to explaining or documenting changes in the analysis. They play a structural role in code and data organization, and do not provide any context about the edits made or their implications for stakeholders.
