Modify viridis palette in ggplot

Question

I\'m trying to color a ggplot by a factor that\'s mostly numerical, like so:

iris %>%
  ggplot(aes(Sepal.Length, Sepal.Width, color = cut(Petal.Length, 0:         


        

Answer 1

Requires a call to scale_color_manual()

iris %>%
  ggplot(aes(Sepal.Length, Sepal.Width, color = cut(Petal.Length, 0:7))) + 
  geom_point() + 
  scale_color_manual(values = c("red", viridis::viridis(6)))
