Dear R-users,
Iam using the boosted regression trees to model the occurrence of
presence/absence data by using environmental factors.
Iam wondering how its possible to print out the data.frame of fitted
functions and variable values that were used in producing the gbm.plot.
For example, values of fitted functions (y-axis) and SegSumT (x-axis) from
the following plot provided in the dismo package example
======================
library(dismo)
data(Anguilla_train)
Anguilla_train = Anguilla_train[1:200,]
angaus.tc5.lr01 <- gbm.step(data=Anguilla_train, gbm.x = 3:14, gbm.y = 2,
family = "bernoulli", tree.complexity = 5, learning.rate = 0.01,
bag.fraction = 0.5)
gbm.plot(angaus.tc5.lr01)
=========================
Best,
Robert
