Iris petal length
WebSince iris is a data frame, we will use the iris$Petal.Length to refer to the Petal.Length column. PL <- iris$Petal.Length PW <- iris$Petal.Width plot(PL, PW) To hange the type of symbols: plot(PL, PW, pch = 2) # pch = 2 means the symbol is triangle The pch parameter can take values from 0 to 25.
