R is among the commonest open source machine learning languages. Some other top ones are Python, Matlab, C++, JavaScript, Java, C#, Julia, Shell, TypeScript, and Scala.

an interesting thing is that your choice of language depends on preference and system requirements.

The following are what you can use R programming language for:

- It is customizable in the sense that users can use their own kernel functions instead of the predefined ones
- Kernel functions can be used to perform Patten recognition problems

## 7. WordCloud

WordCloud is all about a single image having thousands of words. It is known as the visualization of data text.

**Features: **

- It is customizable, as you can have it to your taste

- You need two libraries,
**WordCloud and WordCould 2**, before you can create a WordCloud

## 8. tm

This R machine learning package is known as time mining. Time mining tasks are solved by the framework provided by this package.

- It consists of
**removeNumbers() function:**for removing Numbers from the given text document

- It also consists of
**weightTfIdf() function:**for term Frequency and inverse document frequency

- It has
**tm_reduce() function:**for joining transformations

- It comprises
**removePunctuation() function:**for removing punctuation marks from the given text document, etc.

## 9. MICE Package

This R machine learning package is refered to as Multivariate Imputation via Chained Sequences. Mice package can be used to impute the missing values of machine learning dataset via multiple techniques.

**Features: **

- Some very few important MICE packages are: inspect missing data patterns, diagnosis of the quality of imputed values, analyses completed dataset, store and export imputed data in various formats, etc.

## 10. mlr

mlr is a fantastic R machine learning package. This package allows you to perform many machine learning tasks with just a single package.

**Features: **

- You need
**install.packages(“mlr”)**and**library(mlr)**to install and load this package respectively

- It serves as a connection between several classification and regression techniques

## 11. Arules

This R machine learning package is extensively used as you can perform many operations on it.

**Features: **

- It performs the representation and transaction analysis of data, patterns and data manipulation.

## 12. mboot

This R machine learning package is mostly used for data relating to science. It is known as a model-based boosting package.

**Features: **

- Interaction model is made available by mboot to potentially high-dimensional data

## 13. Party

This R machine learning package can be used for recursive Partitioning. It is known as a computational toolbox.

**Features: **

- Ctree() is the key function of this package and it syntax is
**ctree(formula,data)**

## 14. Parsnip

This R machine learning package works in a similar way to **mlr**. Parsnip can be used to sort out linear regression problems.

**Features: **

- It takes away the problem of referring to multi-packages for a certain machine learning algorithm

## 15. Ranger

This is one of the most loved R machine learning packages. No one loves slow computation of packages, Ranger does computation in a very fast way.
