Re-evaluating the tree in the random forest
Dear mailinglist members,
I was wondering if there was a way to re-evaluate the
instances of a tree (in the forest) again after I have
manually changed a splitpoint (or split variable) of a
decision node. Here's an illustration:
library("randomForest")
forest.rf <- randomForest(formula = Species ~ ., data
= iris, do.trace = TRUE, ntree = 3, mtry = 2,
norm.votes = FALSE)
# I am going to change the splitpoint of the root node
of the first tre...

rpart minimum sample size
Is there an optimal / minimum sample size for attempting to construct a
classification tree using /rpart/?
I have 27 seagrass disturbance sites (boat groundings) that have been
monitored for a number of years. The monitoring protocol for each site
is identical. From the monitoring data, I am able to determine the
level of recovery that each site has experienced. Recovery is our
