Activity: Recreating Plots with Base Plot Methods

The following code can be used to load the datasets library:

library(datasets)install.packages("ggplot2")library(ggplot2)

The following code can be used to load the data:

data("iris")data("mpg")

The following code can be used to create a scatterplot to plot petal width without an axis label:

plot(iris$Petal.Width)

The following code can be used to create a scatterplot to plot petal width without axis labels:

plot(iris$Petal.Width, iris$Petal.Length,     main = "Petal Length vs. Petal Width",     xlab = "Petal Width",     ylab = "Petal Length")

The following code can be used to create scatterplots in 1x2 grids to plot petal length and width with axis labels:

par(mfrow = c(1,2))plot(iris$Petal.Width, iris$Petal.Length, ...
