May I ask for a pointer to documentation of how to use category data
(text categories), which I would like to graph as present/absent at
stations along a transect.  

Thanks for any pointers,

Alan Davis

I have steadily endeavored to keep my mind free, so as to give up any
hypothesis, however much beloved -- and I cannot resist forming one 
on every subject -- as soon as facts are shown to be opposed to it.  
                                  -- Charles Darwin (1809-1882)

The right to search for truth implies also a duty; one must not
conceal any part of what one has recognized to be true. 
                                  -- Albert Einstein 

As we enjoy great advantages from the inventions of others we should
be glad of an opportunity to serve others by any invention of
ours, and this we should do freely and generously.
                                  -- Benjamin Franklin
