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.)
