Artificial intelligence is an emerging technology. It is impacting the interactive activities of users through the internet. It possesses the ability to change the way that humans interact, not only with the digital and electronic world but also with each other. It is basically a form of technology with human-like intelligence that can learn, perceive, plan, and process languages. There are two categories of AI, which include “narrow AI” or “general AI.” Narrow AI is domain-specific that we interact with today. By domain-specific, we mean, for instance, language translation. General AI is theoretical and not domain-specific. Just to remain in the context, we would focus only on narrow AI. It is a machine language – a field of computer science for the development of new algorithms and models. Conversely, we can say machine language is an application of Artificial Intelligence. The list of machine languages is vast, with several different categories. Here we are going to discuss R – a programming language in detail. The language falls in the category of Array languages. So, what is R? R comprises many properties. It is a machine language software that provides an open-source environment for statistical programming and visualizing. There are many R machine learning packages, which we will be discussing in detail. You can find seamlessly designed AI solutions such as R learning packages in the market by machine learning solution companies such as Folio3.

Best R Machine Learning Packages

21 Best R Machine Learning Packages 

The most commonly asked question by potential data scientists is, “What is the best programming language for Machine Learning as a service?” The answer to this question always ends up in a debate about whether to choose R, Python, or MATLAB for Machine Learning. Choosing the programming language for machine learning depends on the requirements of a data problem, the preferences of the data scientist. According to the Kaggle survey, open-source R is the preeminent choice among data specialists who want to understand and explore data by using statistical methods and graphs. There are many R machine learning packages and their advanced implementations for the top machine learning algorithms. Every data specialist must be familiar about them to explore, model, and create a prototype of the given data. Since R is an open-source language, so people can approach it from anywhere in the world. From data collection to reproducible research, you can find a Black Box written by someone else that you can use in your program directly. The Black Box is nothing but a Package in R, which is a collection of pre-written reusable codes. Here are the few basic R learning machine packages:


The CARAT package denotes as Classification and Regression Training. The purpose of this package is to integrate training and model prediction. It allows data specialists to run several different algorithms for a given problem. It also facilitates in investigating the ideal parameters for an algorithm with measured experiments.

best r machine learning packages is carat

CARAT Features And USP: The grid search method of this package explores parameters with the help of a combination of various methods to evaluate the performance of a given model. After having a look at all the trial combinations, the grid search method discovers the combination that gives the best results. CARAT package is among the best machine learning packages in R. After installing the CART package; a developer can run names (getModelInfo()) to see that 217 possible methods require a single package to operate or run. To build any predictive model, CARAT uses train() function; The syntax of train function is train(formula, data, method). CARAT Documentation Download: CARET package is not only for building models, but it also takes care of splitting your data into test and train, alteration, etc.

2) Random Forest

The concept behind its name is to “combine multiple trees to build your forest.” A Random Forest algorithm is the most widely used algorithm in Machine Learning. Its application includes the creation of a large number of decision trees, and then each observation is entered into the decision tree. The common output attained for a maximum of the observations is measured as the final output.

randomforest r machine learning package

In other words, it takes random samples. Observations are arranged into the decision tree. While using the randomForest algorithm, data specialists have to confirm that the variables must be numeric or factors. Factors cannot have more than 32 levels when applying randomForest. This package allows for solving regression and classification tasks. Training missing values and outliers is one of its many applications. The syntax of this function is: randomForest(formula=, data=)

3) E1071

The name of this package seems a junk value, but this is not the case. It is a very significant package in the R machine learning package. It has very specified functions for implementing Naïve Bayes (conditional probability), SVM, Fourier Transforms, Bagged Clustering, Fuzzy Clustering, etc. E1071 R package implemented the first R interface for SVM. E1071 Documentation Download: The easy way to understand its concept is, let’s suppose if a data specialist is trying to find out what is the probability that a person who buys an iPhone 8 also buys an iPhone 8 Case. It is a type of investigation which depends on conditional probability, so data scientists use an e1071 R package that has specialized functions for implementing the Naive Bayes Classifier.

e1071 r machine learning package

Data scientists use Support Vector Machines (SVM) when they have a dataset that is impossible to separate in the given dimensions, and there is a need to promote that data to higher dimensions to classify or regress it. The syntax for SVM is: SVM(Species ~Sepal.Length + Sepal.Width, data=iris)

4) RPart

Rpart stands for recursive partitioning and regression training. Classification and regression are the two primary purposes of this package. It involves the two-stage procedure. The output model is then represented in the form of binary trees. The general way to plot any function using the Rpart package is to call plot() function. The results might not be appealing by just applying the basic plot() function, so there is a substitute that is the PRP() function. It is an influential and flexible function in rpart.plot package. It is frequently denoted as the authentic Swiss army knife for plotting regression trees.

RPart r machine learning package

rpart() function helps to create a relationship between dependent and independent variables so that a business can understand the difference in the dependent variables based on the independent variables. The syntax is: rpart(formula, data=, method=, control=) This formula implies as follows: Data implies the name of the dataset. The method implies the objective. Control implies the system requirement.

5) KernLab

KernLab is a package for SVM, kernel feature analysis, ranking algorithm, dot product primitives, Gaussian process, and a spectral clustering algorithm. KernLab’s most common use is for SVM implementations. It comes in use when it is difficult to solve clustering, classification, and regression problems.  It has several kernel functions that include tanhdot (hyperbolic tangent kernel Function), polydot (polynomial kernel function), laplacedot (laplacian kernel function) and many more to perform pattern recognition problems. KernLab has its predefined kernels, but the user has the flexibility to create and use their kernel functions.

6) Nnet

Data scientists use this package when there is a need to use an artificial neural network (ANN) as it is based on an understanding of how a human brain functions. It is one of the widely used and easy to implement a package of neural networks, but it is restricted to a single layer of nodes. According to several studies, more nodes are not required because they do not contribute to improving the performance of the model but rather increase the calculation time and complexity of the model. This package does not offer any particular set of methods for finding the number of nodes in the hidden layer. Thus, when data specialists apply nnet, it is most likely recommended that they arrange it in such a way that a value falls between the number of input and output nodes.

nnet r machine learning package

The syntax for this package is: nnet(formula, data, size) To view the documentation of its function, go to this link:
