library(ggplot2)
data(mpg)
creates a boxplot in ggplot to visualize the distribution of highway mileage (hwy) for different car categories based on the number of cylinders (cyl). It uses a pastel color palette to differentiate the boxes for each cylinder category.
box_plot <- ggplot(mpg,aes(x=factor(cyl),y=hwy,fill=factor(cyl)))+
geom_boxplot(alpha=0.5)+
labs(
title="highway milage distribution by number of cylinder",
x = " number of cylinders",
y = " highway milage")+
