In general the best way to arrange a table is
not to do it and think of an appropriate graph
instead.  That is a  reasonable (though probably
wrong) explanation of why it is hard to find
suggestions.

Does anyone have any suggestions about books or papers on table design that
would be the equivalent of the books mentioned for graphics?  I have looked
at quite a few, but I have found that very few specifically discuss
describing large complex datasets in tables (such as from clinical trials).


Specifically, I have read Lang's "How to Report Statistics in Medicine" and
Few's "Show me the Numbers", but these seem to focus on simple single
statistic displays or re-displaying tables as in standard software.  What
I'm looking for is descriptions of the best way to arrange tables for
perception and interpretation.

          Are there script files for "The Elements of Graphing Data"?
Before I read David Thompson's email, I didn't know that scripts and data
for "Visualizing Data" were available.

          I agree with Frank that these are "awesome books", and I'd like to
explain briefly why I think so.

          For me, the the seminal contribution of "The Elements of Graphing
Data" is its chapter summarizing research in visual perception:  What can
you do in designing graphics so people get more information in less time?
The contents of this chapter have helped me, I believe, develop more
effective graphics.

          The graphics in the two books seem to be the foundations of
Trellis / Lattice graphics.  They do not discuss how to create the graphics
using S-Plus or R, only why those kinds of graphics are useful.  The data
and script files increase substantially the value of the book(s).  When I
read the books, I remember being frustrated by not knowing how to create the
graphics.  Thanks to David Thompson's email, I can now revisit "Visualizing
Data".

Could anyone comment on the relative merits of two of Cleveland's
books:
"Elements of Graphing Data" (94), and "Visualising Data"  (93) ?

I'm looking for fairly basic account of the principles of graphical exploration, with particular reference to Splus, which is not too
heavy
on statistical theory.  My interest is medical data.  If the scripts
and
datasets used in either are publicly available that would be a big
plus.
Many thanks

These are awesome books and everyone who looks at data should own them.
The Elements of Graphing Data book is the best how-to for scientific graphics. There is a web site with scripts from the books although Cleveland used a few customizations.

That scripts link (at least for Visualizing Data) is:
