Well the fact is, that I as a beginner was looking for who I could plot
normal functions, so one more example would have helped me.

That is probably true.

Searching for »s3 m« in [1] did not give me a good explanation. I have
not yet read the language manual.
By trial and error I still suggest to add the following.
# Plot the graph of a function f(x) = x^3 with the points connected by lines.
# If you want to plot the graph as a curve please look into `curve()`.
y <- seq(1:5)
plot(y, y**3, type="l")
This would have helped me as a beginner.
Thanks,
Paul
