Plotting Basics

Plot

x <- c(1, 3, 1, 2, 5, 1)
y <- c(1:10)
 
plot(x)
plot(x, type = “o”, col = “green”)
title(main = “Random Data”, col.main = “blue”, font.main = 4)
lines(y, type = “o”, col = “red”)

Exercise:

• Make the points triangles rather than circles.
• Make the lines dashed.
• Add a legend.

data(iris)
pairs(iris)

What is the output of this function?

Exercise:

• What is the distribution of petal lengths? (hint: make a histogram)
• What is the spread of petal lengths per species? (hint: use a box plot)
