[R] easing out of Excel

[Shawn Way]

Definitely check out the lattice package.

One other option is to use sweave/latex mixed with RODBC.  This can be
used to produce PDF's for easy distribution as well.  I would also
consider operating this in a batch mode, the R/sweave/latex works very
well this way.

Since you are looking for summaries within groups, you should look at
the
lattice package and some of the plots that you can produce with it
(maybe
for each product line you can produce a lattice/trellis graph with each
panel
representing a region and different colors symbols within panels to
represent
different customers).

If we had more of an idea of what you are looking for, we could give
better
suggestions.

It looks like you want the reports fully automated and the final result
as HTML
(to be viewed with a browser), I suggest you look at the R2HTML package
and
the sweave function (this lets you write a report in HTML with r-code
in place of 
graphs and output, then a quick run through sweave and you have a final
report
in HTML ready to be viewed).

There are also several tools available for running R through CGI, go
to: 
http://www-r.project.org/ and click on "R web-servers" under the
"Related Projects"
heading in the left column to get details.

Hope this helps,
