## The 20 Best R Machine Learning Packages in 2020

Almost all novice data scientists and machine learning developers are being confused about picking a programming language. They always ask which programming language will be best for their machine learning and data science project. Either we will go for python, R, or MatLab. Well, the choice of a programming language depends on developers’ preference and system requirements. Among other programming languages, R is one of the most potential and splendid programming languages that have several R machine learning packages for both ML, AI, and data science projects.

As a consequence, one can develop his project effortlessly and efficiently by using these R machine learning packages. According to a survey of Kaggle, R is one of the most popular open-source machine learning languages.

**Best R Machine Learning Packages**

R is an open-source language so people can contribute from anywhere in the world. You can use a Black Box in your code, which is written by someone else. In R, this Black Box is refereed to as a package. The package is nothing but a pre-written code that can be used repeatedly by anyone. Below, we are showcasing the top 20 best R machine learning packages.

**1. CARET**

The package CARET refers to classification and regression training. The task of this CARET package is to integrate the training and prediction of a model. It is one of the best packages of R for machine learning as well as data science.

The parameters can be searched by the integration of several functions to calculate the overall performance of a given model by using the grid search method of this package. After successful completion of all trials, the grid search finally finds the best combinations.

After installation of this package, the developer can run names (getModelInfo()) to see the 217 possible functions which can be run through only one function. For building a predictive model, the CARET package uses a train() function. The syntax of this function:

When a single image consists of thousands of words, then its called a Wordcloud. Basically, its a visualization of text data. This machine learning package using R used to create a representation of words, and the developer can customize the Wordcloud according to his preference, like arranging the words randomly or same frequency words together or high-frequency words in the center etc.

In the R machine learning language, two libraries are available to create wordcloud: Wordcloud and Worldcloud2. Here we will show the syntax for WordCloud2. To install WordCloud2, you have to write:

**10. tidyr**

Another widely used r package for data science is tidyr. The goal of this r programming for data science is tidying the data. In tidy, variable is placed into the column, observation placed into the row, and the value is in the cell. This package describes a standard way of sorting data.

For installation, you can use this code fragment:

install.packages(“tidyr”)

For loading, the code is:

library(tidyr)
