WebR has several systems for making graphs, but ggplot2 is one of the most elegant and most versatile. ggplot2 implements the grammar of graphics, a coherent system for describing … WebI predict that hwy will be plotted against displ as a scatter plot, with the color of the dot depending on the drv variable. superimposed on these points will be a smoothened conditional mean line, also colored based on the drv variable, since these were declared globally. ```{r chp3_exercise_predict}
Web#Answer :Because the purpose of those plots is to show the difference between no groups, using a group aesthetic, and using a color aesthetic, which creates implicit groups. In that example, the legend isn’t necessary since looking up the values associated with each color isn’t necessary to make that point. Web3.2.2 Creating a ggplot To plot mpg , run this code to put displ on the x-axis and hwy on the y-axis: ggplot(data = mpg) + geom_point(mapping = aes(x = displ, y = hwy)) The plot shows a negative relationship between engine size (displ ) and fuel efficiency (hwy ). In other words, cars with big engines use more fuel.
WebThe first plot compares displ vs hwy and rows are facetted by drv while there is no facetting by columns. ggplot(data = mpg) + geom_point(mapping = aes(x = displ, y = hwy)) + facet_grid(. ~ cyl) The second plot compares displ vs hwy and columns are facetted by cyl while there is no facetting by rows.
