No, par does not work with ggplot. The par function sets or queries the graphical parameters for the base R plotting system, which differs from the ggplot2 plotting system. The ggplot2 plotting system is based on the grammar of graphics, which allows you to create graphs by specifying the components and layers of your plot. The ggplot2 plotting system also provides a consistent theme and style for your plots. To customize the appearance and behavior of your ggplots, you need to use different functions and options from ggplot2 or other related packages. For example, you can use: The `theme()` function or one of the predefined themes (such as `theme_bw()`, `theme_classic()`, or `theme_minimal()`) to modify the appearance of your plot The `scale_*()` functions to modify the axes or legends of your plot The `coord_*()` functions to modify the coordinates or aspect ratio of your plot The `facet_*()` functions to create multiple panels within one plot based on one or more factors
