I'm interested in modifying a regression tree algorithm to use the difference between a control and a dosed sample as its dependent variable. I was wondering if anyone knew where I could find code to implement a basic chaid algorithm. Is it possible to access the code inside of R? Is there another place I can find the basic algorithm already coded.
don't know about your specific target, but as a general question of seeing the code: to see a function's code in R, just type its name at the prompt without parentheses - that will show the code, rather than invoke the function.
