Chapter 4 Problem 4

Using the iris dataset in the datasets package (dataset package belongs to Base R and so you don’t need to download the package.) replicate the plot below ing the following settings.

• Set size = 6 for the size of points
• Set alpha = 0.5
• Use theme_minimal()

ggplot(iris, aes(Sepal.Length, Sepal.Width)) +
  geom_point(aes(shape = Species, color = Species), size = 6, alpha = 0.5) + 
  theme_minimal() +
  labs(
    title = "Scatterplot",
    subtitle = "Sepal.Length Vs Sepal.Width",
    caption = "Source: iris"
  )
