Whether R is user-friendly depends on the user... It does often have
the advantage of actually being able to do what people need. If you
can follow some simple examples, like those on the help pages, and
do the relevant substitutions and modifications for your own problems,
then you're basically set. There is a syntax that you have to follow,
and some associated fault-finding when you type something wrong, but
you can get quite far without actual programming. It's something that
is there for you when you need it.
