Changing the Color of Base Plots

Let's see how you can use the col option provided by the plot() function to change a plot into a few different colors. Follow the steps given below:

1. Use the col option to turn the plot from the last exercise blue as follows:

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

2. Use the col option to turn the plot from the last exercise yellow using the hexadecimal color code 111111:

plot(iris$Petal.Length, iris$Petal.Width,     main = "Petal Width vs. Length",     sub = "iris dataset",     xlab = "Petal Length",     ylab = "Petal Width",     col = "111111")

Output:
