20.69 The Original C5.0 Implementation
The (Kuhn and Quinlan 2023) package interfaces the original C code of the C5.0 implementation by Ross Quinlan, the developer of the decision tree induction algorithm.
library(C50)
model <- C5.0(form, ds[tr, vars])model##
## Call:

plot(model)I am not aware of any converter from a C5.0 tree to an rpart tree and so fancyRpartPlot() will not be useful here.
