If you're a retro-geek like me with fond memories of slide rules but have long since lost yours, now you can build your own with R. Children's Mercy hospital has R code to draw a template for a slide rule. The code, incidentally, is very well written and commented and makes an excellent example of using R to create arbitrary shapes and diagrams. There are also detailed instructions for assembling and using the slide rule for likelihood ratio tests. (Note: the URL on the slide rule no longer works, but I'm guessing this latter link is what it pointed to.)

Cool. I was - only this morning - thinking about how to use R to do exactly this sort of thing (make a slide rule - but for a different purpose).

If anyone is interested in creating some non-standard slide rule scales, visit my Web page at http://www.mathed.org/slide.html. I have scales for finding the third side of a right triangle and for adding velocities relativistically.
