Hello,
I have a question about splitting label in regression tree.
for example, by using the following command

plot(m.regression.tree.pr,uniform=T,margin=0.05,branch=0.7,compress=F)
text(m.regression.tree.pr,pretty=0)

I get a tree with one label in some splitting node like this
bcu<0.004969

Now I want to set up bcu<0.0050, i.e. just get 4 number after decimal.

Does anyone know how to set up this?

Thanks

Aimin
