- Use the barplot() function and provide a vector or matrix of numeric values representing the frequencies or proportions of the categories
- Use the pie() function and provide a vector or matrix of numeric values representing the frequencies or proportions of the categories
- Use the plot() function and provide a vector or matrix of numeric values representing the frequencies or proportions of the categories
- Use the ggplot2 package and the geom_bar() function with the categorical variable as the x aesthetic
