Formally speaking, вЂњDecision tree is a binary (mostly) structure where each node best splits the data to classify a response variable. Tree starts with a Root which is the first node and ends with the final nodes which are known as leaves of the treeвЂќ.

In the 1960s, In the 1960s, originators of the tree approach described the splitting rules as decision rules. Decision tree has various parameters that control aspects of the fit. In rpart library, you can control the parameters using the rpart.control() function. In the following code, you introduce the parameters you will tune. You can refer to the.

Using the Titanic dataset, learn about its advantages and pitfalls, as well as better alternatives.

Now you plot the decision tree, and you can see how it corresponds to the rpart() output. You do this with a function called prp() , which lives in the rpart.plot package. The rpart package has a function called plot.rpart() , which is supposed to plot a decision tree. Inside rpart, there is therpart() function to build your first decision tree. The function takes multiple arguments: formula: specifying variable of interest, and the variables used for prediction (e.g. formula = Survived ~ Sex + Age).

A decision tree is a flowchart-like diagram that shows the various outcomes from a series of decisions. It can be used as a decision-making tool, for research analysis, or for planning strategy. A primary advantage for using a decision tree is that it is easy to follow and understand.
