homework 6

[Dilem Avşar]

Hello everyone, I am trying to check if my code is true for the first question but I can not plot the graph because I keep getting this error massage "plot.new has not been called yet" Did anyone get the same error?

maybe your code is true, but it is not correct. True≠correct.

that error message means that you are using "points" or "lines" or something like that, that you can only use after using "plot" first

yes sir it is the code that already exists in homework to check the answer and yes i get the error message when it comes to "lines(town&rats, lty=2)"

The complete code says

plot(town$cats, xlab="Days", ylab="Population", type="l")

lines(town$rats, lty=2)

it should work if you do both commands together. If it still does not work, we need to see your computer (zoom?)

So I found that my code was incorrect. Thank you.
