Final answer:
The third drawback of the base plotting system in R is its lack of interactivity, not allowing users to dynamically interact with the plot once created.
Step-by-step explanation:
One of the drawbacks of the base plotting system in R is its lack of interactivity. While base plots provide a solid foundation for creating static graphics, they unfortunately do not allow for dynamic interactions with the plot once it is generated. This means that users cannot zoom into a specific area of the plot, hover to get more information about a data point, or update the plot with new data without redrawing the entire plot. This is particularly limiting when dealing with large datasets or wanting to closely inspect certain aspects of the visualization. Other visualization packages in R, like ggplot2 or plotly, provide more interactive options.
