ggplot increase label font size

To increase the label font size in R ggplot, follow these steps:

1. Use the theme() function to modify the text size using the element_text() function.
2. Within the element_text() function, set the size parameter to the desired font size for the axis labels.
3. Apply the modified theme to the ggplot object using the + operator.

This will result in an increase in the label font size for the ggplot visualizations.
