Just a few thoughts... Good documentation helps everybody - the beginners and the experts (less beginner questions if there is thorough and accessible documentation. I fully appreciate that this is a volunteer effort - I'm just trying to pin down some places where we have documentation issues.

Docs can be in a number of different forms - reference, examples, carefully and throughly explained. I personally find it difficult to understand reference type material until I have seen a worked example, and some of the reference material is a little light on the examples for me, and others like me who thrive on examples. The Linux-HOWTO collection are a good example of step-by-step documentation... If you're an expert, then you can read it fast and skip... otherwise you read every line.

Since R comes as a computer "package" and a statistics "thingy"... the questions on this list come in three forms - those that are very 'package', e.g. "how do I reduce the space between two graphs" - to the statistics questions "how reliable is the coefficient of determination in the presence of outliers" (which shouldn't really be asked here), and then the how do I do 'statistic X' in R - "how do I calculate a confidence interval around the coefficent of determination in R?".

The standard documentation got me so far in learning about R - I got a copy of MASS, S-Programming, "Introductory Statistics with R", and Michael Crawley's new book "Statistics : An Introduction using R" - along with every online book I could find on CRAN and elsewhere. Unfortunately for me, my experience leaves me in between the beginner books and the more advanced texts like MASS, David, Schervish etc... The learning curve is steep - but then like many people, I'd like to be able to do sophisticated modelling with deep understanding and no effort :-)

I feel there is a bit of a hole in the middle of the documentation which could be attacked from both sides - the introduction element is starting to be covered - it's the next step up from that.

And yes before you ask I would like to help - but my statistics knowledge is very poor! Should this conversation go to r-devel?

Thanks for listening,
Sean
