library(ggplot2)
# Box plot
ggplot(iris, aes(Species, Sepal.Length)) + 
  geom_boxplot(fill = "#FFDB6D", color = "#C4961A") +
  theme_minimal()

# Scatter plot
ggplot(iris, aes(Sepal.Length, Sepal.Width)) + 
  geom_point(color = "#00AFBB") +
  theme_minimal()

  • Usage in R base plots:
barplot(c(2,5), col = c("#009999", "#0000FF"))
