[S] Tree mystery (minor correction)

["Buttrey, Samuel" <sebuttre@monterey.nps.navy.mil>]

Sorry. When I said:

> > test <- data.frame (y = as.factor (c(0, 0, 1, 1, 1, 1)), x = c(0, 1,
> 1.00001, 1.00001, 2, 2))
> 
> The ideal tree would split x between 1 and 1.00001, perhaps at the
> mid-point, 1.000005.

the next line should have read

"then both observations where y = 0 would go to the left, and all four where
y = 1 would go to the right."

Sorry,
