20.27 Rules from Decision Tree

We can use rattle::asRules() to convert the decision tree to a set of rules:

asRules(model)
## 
##  Rule number: 7 [rain_tomorrow=Yes cover=8014 (6%) prob=0.79]
##    humidity_3pm>=72.5
##    humidity_3pm>=83.5
## 
##  Rule number: 13 [rain_tomorrow=Yes cover=3275 (3%) prob=0.65]
##    humidity_3pm>=72.5
##    humidity_3pm< 83.5
##    rainfall>=2.7
## 
##  Rule number: 25 [rain_tomorrow=Yes cover=1768 (1%) prob=0.58]
##    humidity_3pm>=72.5
##    humidity_3pm< 83.5
