[R] Rpart, custom penalty for an error

seem to be cloned success-observations. I'd like to split the tree just as weights parameter allows me to, keeping the original number of observations in the tree plot. Is it possible? If yes, how? Kind regards, Maciej -- Maciej Bliziński <[EMAIL PROTECTED]&g

Re: [R] How to intepret a factor response model?

Thanks a lot for the answers (prof Ripley and Ted). I'm trying to analyze a survey. Most of the variables are of factor type, with values for example {"no_at_all", "a_little", "mostly", "a_lot"}. I thought about mapping those answers to numbers, but I didn't know what numbers should I assign them

[R] How to intepret a factor response model?

Hello, I'd like to create a model with a factor-type response variable. This is an example: > mydata <- data.frame(factor_var = as.factor(c(rep('one', 100), rep('two', > 100), rep('three', 100))), real_var = c(rnorm(150), rnorm(150) + 5)) > summary(mydata) factor_var real_var one
