You can't just pick out lines and expect them to run on their own.  The 
context is

# make the bins smaller, make a plot of density
hist(eruptions, seq(1.6, 5.2, 0.2), prob=TRUE)
lines(density(eruptions, bw=0.1))
rug(eruptions) # show the actual data points

We do arrange to run the code from that manual to test every release.
And that block of lines does work.
