[R] tree-ID in any segmentation package available?

Dear R-helpers, I am looking for a segmentation package that gives some tree identifier as output for every observation in the data set (my response variable is binary). I have skimmed through rpart, ada and adabag: The output trees gives you the formula, but I have to run several thousand

Hi, I am looking forward if some of you could help me with this. I have been looking R-functions to conduct tree-ring analysis in R. I know that exists a COFECHA version in R developed by C. Bigler. But I don't know if is there another collection of functions to do dendroclimatological

[R] Tree vs. Rpart

I'm using classification trees for the first time. I understand the difference between these 2 packages, but I'm having a bit of trouble interpreting the results. I have 3 different response variables, but I'll only use 1 in this discussion. I first ran Tree. I was happy with the results, 6
