plot(iris$Petal.Length ~ iris$Species)

• Will make a dotplot

• Will make a boxplot

• Will make a pie plot

• Will make a barplot

plot(iris$Species)

• Will make a dotplot

• Will make a boxplot

• Will make a pie plot

• Will make a barplot

Which won't work

• plot(iris$Species)

• plot(Species, data = iris)

• plot(Sepal.Length ~ ., data = iris)

• library(dplyr)

  iris %>%

  plot()

The next code will print:

library(ggplot2)

ggplot(iris, aes(x = Sepal.Length, y = Sepal.Width))

• Nothing

• An empty frame

• A dot plot

• A box plot

The code will give:

library(ggplot2)

ggplot(iris, aes(x = Species,

y = Sepal.Width,

fill = Species)) +

geom_boxplot() +

geom_jitter()

• A boxplot with all boxes the same color

• A boxplot with different color for each species and all the points in black

• A boxplot with different color for each species and all the points the same colors than the boxes

• A dot plot
