Dear list members, Can anyone tell me how the notches in boxplot(Y~X,notch=T) are calculated? What do these notches represent exactly?

Best regards Chris.

I am brand new to Ruby and Ruby on Rails, and I already have e-novatove WAMP set up and running perfectly for PHP/MySQL development. Can I set this up to use Ruby without messing it up for PHP/MySQL? It took me a while to get it working for PHP/MySQL and I don''t want to do anything to break it. Any help would be greatly appreciated. Thanks, Jim -- Posted via
