To be completely honest though, the R site looks horribly out-dated (Fig-
ure 3-21), and the software itself isn't very helpful in guiding new users.
You need to remember though that R is a programming language, and
you're going to get that with any language you use. The few bad things that
I've read about R are usually written by people who are used to buttons
and clicking and dragging. So when you come to R don't expect a clicky
interface, or you will of course find the interface unfriendly.

But get past that, and there's a lot you can do. You can make publication-
quality graphics (or at least the beginnings of them), and you can learn to
embrace R's flexibility. If you like, you can write your own functions and
packages to make graphics the way you want, or you can use the ones that
others have made available in the R library.
