Mark, The below is not directly reproducible. There is no "MV" or "PT" variable in the dataset you reference. I am assuming you meant:
dat <- read.table("http://statcourse.com/research/boston.csv";, ,
sep=",", header = TRUE)
fit <- rpart(MEDV ~ CRIM + ZN + INDUS + CHAS + NOX + RM + AGE + DIS +
RAD + TAX + PTRATIO + B + LSTAT, data = dat)
plot(fit)
which creates the plot I attached.
Cheers,
Josh
