Subject: [Rd] Help Documentation (PR#6717)
Message-ID: <20040329141430.11BD6FB9A@slim.kubism.ku.dk>

Ivo,

Let me address your points in reverse order:

1. There is a `wishlist' category for bug reports, which I guess you've
overlooked.

2. There is also a `Contributed Documentation' section on the R web site,
which you can submit your contribution.  As well, there are a few
introductory level documents there already that you might be interested.

3. I must repectfully disagree about adding/changing the help pages just so
beginners or novices can learn R better.  If the help pages are your sole
source for learning R, I can only say that you could do a lot better.  The
help pages are supposed to be complete and accurate documentation of the
topics they cover.  The ones in R do a extremely good job at that, and, I
must say, are much more user-friendly than most *nix man pages.  

If you had familiarize yourself with just the official newbie doc, `An
Introduction to R', that would have solved most, if not all, of your
questions.  If you have not done that, there will be little enthusiasm to
what you have to propose.

Cheers,
Andy
