Hi all,
Can anyone who is familar with CART tell me what I missed in my tree code?
library (MASS)
myfit - tree (y ~ x1 + x2 + x3 + x4 )
# tree.screens () # useless
plot(myfit); text (myfit, all= TRUE, cex=0.5, pretty=0)
# tile.tree (myfit, fgl$type) # useless
#

There is not function tree() in MASS. I guess you have loaded package
tree?
