# Iris Data Set
head(iris)

# plot first plot for Sepal Length 
with(iris, plot(Sepal.Length, col = "red",type= "o"))
# set new plot
par(new = T) 

# plot second plot, but without axis for Petal Width
with(iris, plot(Petal.Width, type = "l", xaxt = "n", yaxt = "n", xlab = "", ylab = ""))
# define y-axis and put y-labs
axis(4)

with(iris, mtext("Petal.Width", side = 4))
