# How to Implement Decision Tree in R ?

The dt package is used to implement decision tree During the process of building a decision tree, you have to create a number of variables from the input data. For example, in our model, we’ll use the variable Sales. This variable will be used to represent the percentage of vegetarian guests. There are a number of ways to fill a decision tree model. The first step is to select the type of decision you want to make. There are a variety of decision tree models available, and there are many different methods. Simply type the function in R to create a decision tree model.

The next step is to split the decision tree into sub-nodes. The more sub-nodes you have, the more complex your decision tree will be. Your decision tree complexity will be determined by the error rate. You can use R’s party package and class method. You can also use the rpart () function to divide a node into sub-nodes. After the nodes have been divided into their sub-nodes you can assign a class to the new data.

The second step in the process of creating a decision tree is partitioning. In decision-tree design, a data set is a graph with each node representing a class. A branch is the representation of each node in the tree. A parent node is a sub-node. Its child is a Sub-node. Using the c5.0() function, you can modify the output of a decision-tree by modifying the rules argument. Hence, you can now use R to split nodes into groups.

Moreover, decision trees can be used to classify new unclassified data. This is possible by using a recursive partitioning basis. Recursive partitioning achieves maximum homogeneity in a new partition. There are many algorithms for splitting nodes, and each of them affect the accuracy of the decision tree. You must remember that the higher the cp value, the larger the tree, and the higher the likelihood of an error.

Once you have created the decision tree you can divide each node into a series or sub-nodes. The number of sub-nodes will determine how complex the algorithm is. However, the more sub-nodes the decision tree contains, the more the complexity. If you want a complex decision tree, use the c5.0 function. Afterward, you can change the type of data by altering the c5.0() parameter.

It is simple to use a decision tree in R. All you need to do is use the function to define a classifier in R. A classification tree consists of sub-nodes, each of which has its own class. You can even categorize the same data in a different way using the same procedure. It is flexible and easy to use and can be used in many situations.

Once you have established a data structure, it is time to create a decision tree. The decision tree is composed of sub-nodes or branches. This can be used as a training or testing set. You can use, for example, the c5.0() function. Next, change the p values in your ANOVA to a particular value. This will result in a more complex decision tree.

There are many different ways to implement a decision tree. There are two main types of decision trees: non-classifying and conditional. The most popular choice for regression and classification problems is the Generality CART. It can also be used to solve problems with missing values. If you have data that is not yet classified, you can use the CART. The Generality CART can be used to process these problems.

Divide the data into test and training sets to create a decision tree. You can split the data into separate classes based on the size and number of nodes. Each node has its unique IG. IG is the measure for a decision’s likelihood. Each level of a decision tree has its own independent value. Therefore, the data must be labelled to be classified.
