Printing an rocTree object

Source: R/print.rocTree.R

The function prints an rocTree object. It is a method for the generic function print of class "rocTree".

# S3 method for rocTree
print(x, digits = 5, tree = NULL, ...)

Arguments

x

an rocTree object.
digits

the number of digits of numbers to print.
tree

an optional integer specifying the \(n^{th}\) tree in the forest to print. The function prints the contents of an rocForest object by default, if a tree is not specified.
...

for future development.
