classification - R package "tree": how to control the maximum tree depth? -
the r package "tree" restricts maximum tree depth 31. if function tree
applied large dataset, limit reached:
> library("tree") > library("elemstatlearn") > data <- list(image=as.matrix(zip.train[,-1]), digit=as.factor(zip.train[,1])) > t <- tree(digit~image, data, split="gini") error in tree(digit ~ image, data, split = "gini") : maximum depth reached calls: source -> withvisible -> eval -> eval -> tree -> .c
is there way tell tree
stop growing tree when maximum tree depth reached, rather aborting error? (in other words: there equivalent maxdepth
parameter of rpart.control
?)
