Sorry, I wasn't very helpful. Let me try this again. I have attached a
subsample of the data which still gives me the same error as when I use the
full data file. I am trying to make a decision tree using rpart. This is my
code and output.

I am trying to make a decision tree using rpart. The function runs very

summary command I get this:
> summary(bookings.cart)
Call:
rpart(formula = totalRev ~ ., data = bookings, method = "class")
