The `xlim()` function in R is used to set the limits of the x-axis in a plot. By defining the range of values that are displayed on the x-axis, this function allows for better control over how data is visualized, making it easier to highlight specific aspects or trends in the dataset. It plays an important role in customizing plot aesthetics, helping to ensure that plots are both informative and visually appealing.
