R help - May 2008 - how to save many trees within a loop?

Hi,
I would like to save many trees created in a loop as
different ones. I can plot them, but I can not get the
whole tree properties saved. I paste the script below
Also, How can I perform multivariate trees?, that is
predicting a vector o values, not a simple scalar
observation.
Thanks in advance
Angel

for (i in 1:7){#loop para hacer arb
arb=arb[i]#contador
arb=tree(GF[,i]~Temp+Area+ISS+Zmix+Kd+Alk+DIN+SRP+RSi+CLA+Chloa,
data=GF)#
plot.tree(arb); tit=colnames(GF[i]);title(tit); 
text(arb,digits =2);#dig significativos

Save the for.. results in a list, and save/load the list. Please, provide a
self-running examples next time.

library(tree)
trees = list()
# Simple for - replacement
trees[["Length"]]= tree(Species ~Sepal.Length+Petal.Length, iris)
trees[["Width"]]= tree(Species ~Sepal.Width+Petal.Width, iris)
save(trees, file="trees.Rdata")
rm(trees)
# Reload
load("trees.Rdata")
## Well... add the decoration
plot.tree(trees[["Length"]])
