Enhance Scatterplots with ggplot Shapes plot in R

Key Points ggplot shapes represent the points in a scatter plot, and they can be used to distinguish different groups of data, highlight outliers, or add more information to the plot. We can use 25 different ggplot shapes, ranging from simple circles and squares to more complex shapes like stars and triangles. We can customize the shapes, colors, sizes, and fill to suit our needs. We can map a variable to the shape of the points using the aes() function, which will create a different point shape for each variable level and add a legend to the plot. We can use geom_jitter() and geom_count() to deal with overplotting, which occurs when there are too many points in the plot that overlap with each other. geom_jitter() adds a small amount of random noise to the x and y coordinates of the points, and geom_count() adds points with sizes proportional to the number of observations at each position. We can use geom_smooth() to add a regression line and a confidence interval to the plot, which can he…
