[R] Cook-distance-type plot (vertical bars)

[Paul, David A]

I'm (relatively) new to R myself, and recently found 
the documentation by Dr. William Cleveland et al at

http://cm.bell-labs.com/cm/ms/departments/sia/project/trellis/
http://cm.bell-labs.com/cm/ms/departments/sia/project/trellis/software.writi
ng.html

It has been helpful, and covers S/Splus trellis graphics.  In R, the
equivalent is known as "lattice" graphics, and the syntax is
virtually identical.  Earlier today, Dr. Peter Dunn posted a 
notice to the R listserv announcing a workshop in Australia being
led by Dr. John Maindonald... in that announcement, you will find

"...John Maindonald, the author of the forthcoming book 'Data Analysis 
and Graphics Using R: An Example-Based Approach' (with John Braun)..."

so apparently there is a forthcoming book detailing the graphical
capabilities of R.  I'm eagerly awaiting the opportunity to buy it
and digest its contents!  Until then, I think the links to the 
.ps and .pdf files above should serve well.


Best wishes,

P.S. - You should keep in mind that there are two classes of 
graphical functions in S/Splus/R: "regular" functions and
"trellis/lattice" functions.  They operate very differently.
After using a few of each, I must say that I am very impressed
with the power and flexibility of the trellis/lattice 
plotting functions.

Thanks to all who responded, and so promptly too: it works exactly as you 
describe.

Thomas Lumley is quite right, it's produced by plot() (not termplot()), and 
it is mentioned on p31 of "R for beginners". My mistake.

In the interest of self education, is there a more comprehensive source for 
plot-types that I should read? Ideally, this would be something with lots 
of figures, so that I could browse the figures to find what I want to do, 
and then look up how to do it. "R for Beginners" goes some way along this 
path, but perhaps there's something more comprehensive?

Thanks again,

-Frank
