# Tree complexity using gbm

I am using the gbm package and I am using the gbm.step function. In the ?gbm.step I see tree.complexity sets the complexity of individual trees. Is this equivalent to the depth of the tree ?

There is a vignette by Jane Elith and John Leathwick for GBM's in dismopackage . The package actually uses gbm.step implementation from gbm package.
So, it seems it is a depth as you supposed.
