Suggestion for posting guide
I have a suggestion for the posting guide. One problem with some posts is that
they do not provide an example that can be reproduced. I think that many
people just do not know how to easily specify some data and some technical
assistance should be provided in the posting guide. If the problem
depends on specific data they should be made aware, in the posting guide, of:

Proposal for New R List: Criticism? Comments?
Folks:
I would like to propose a new R list, tentatively labeled r-contents. I wish
to briefly explain the purpose and format here and solicit public comments,
pro or con, so feel free to criticize or suggest a better name and other
improvements or alternatives.

and several hundred contributed packages comprising

draft of posting guide
Here is a first draft of a guide for posters to r-help and
r-devel. Suggestions on how to improve any aspect of it are
most welcome. Suggestions on ways to make it more concise
are especially welcome. Comments on which parts you like
or don't like are welcome. Rather than clutter up R-help with
lots of small corrections etc, please send them to me, and I
will try to incorporate and

Finding Instances of a Pattern Throughout Data Set
I have approximately 2.5 million rows from a number of sensor
readings. Having plotted these, I can see a given pattern (say a spike
in the amplitude away from the mean). I would now like to automate
this procedure as we're expecting a great deal more data in the near
future. Is there any package or function that will make this possible?
Many thanks! I suppose, I could do something like:

revision of posting guide
I've placed a revision of the posting guide at http://pws.prserv.net/tap/posting-guide-draft2.html. (Posted there to make the HTML formatting easy to read.) I've tried to incorporate the suggestions people posted and mailed to me. Quite a few were of the form "too long, but you should add this..." :-)

Suggestion for the posting guide
I was preparing an e-mail for the help list and ran across a quandary.
When asking for help it is useful to include the code/data so others can
run your code and test it. I was running code on a data frame and wanted
to include a small version of the data frame. The data frame was based
on experimental data. What is the best way to do this? I didn't want to
send an attachment so a wrote code

Offline indexing with Drb, online using index in Rails?
I have a Rails application where I need to search. Every time an update
happens to something I need to update the index for the changed and
related document. As I currently have to run on Windows (and therefore
can''t use the native extension) it is quite slow to index sometimes and
the user have to wait a couple of seconds for the save operation to
return.
A thought is to put this

increasing speed for permutations of glm
Dear R Programmers,
I am trying to run a Poisson regression on all pairs of variables in a data
set and
obtain the permutation distribution. The number of pairs is around 100000.
It seems my code will take weeks to run, unless I try something else.
Could you give me any suggestions on how to improve the speed of the
code below, or any general suggestions on how I may accomplish this task.
Thanks
