The JSS editorial board is considering a JSS section "R Snippets",
possibly edited by our editors Kurt Hornik and Roger Koenker,
which will have "interesting pieces of R code", with only a
minimal amount of text /comments. Reactions ?
Excellent!
Yes, but...

Yesterday I went through Paul J's site and looked at several of his
code snippets, quite a few of them originally due to myself, and I got
struck by how esoteric many of the issues seemed compared to how
interesting and challenging they were originally. Perhaps it would be
an idea to use a format of exercises or challenges? (Of course, this
assumes that the reader already knows about S and R, which could be a
problem if the purpose is to "spread the gospel".)

-p

The 'exercise' or 'challenge' format seems a neat idea... a bit like the
'chess' challenges you can sometimes find in the magazines (you are
given a certain 'game configuration' and you need to do something in a
given number of moves)...
A short problem is set, and the ways to solve it are
detailed (eventually in the next issue to let people think about it, or
publishing the answers sent (in categories 'shortest' , 'fastest', ...))

... I found myself taking the 'how do I do that' mails on r-helps as
such... and learning from reading the answers... may be what has been
already asked on this list represents enough starting material.
