## Programming Features of R

R includes a number of programming capabilities that we’ll go through below:

### 1. Data Inputs and Data Management

Data inputs such as data type, data import, and keyboard typing are all examples of data inputs.

Data management such as data variables, operators.

### 2. Distributed Computing and R Packages

**Distributed Computing** – For the R programming language, distributed computing is an open-source, high-performance platform. To minimise execution time and analyse massive datasets, it divides work across numerous processing nodes.

**R Packages** – R packages contain R functions, built code, and example data. R instals a set of packages by default after installation.

With over 10,000 packages in the CRAN Repository, R offers a wide choice of options. The vast majority of these Packages are used to carry out Data Science tasks. While some of the most popular have previously been discussed, the following is a list of some of the most extensively used R Packages in Data Science:

**Ggplot2**: Ggplot2 is one of the most popular R packages for visualisation that requires only a few lines of code. It is inspired by the Grammar of Graphics. Data scientists just need to tell Ggplot2 how to map variables to aesthetics and which graphical primitives to employ, and it will take care of the rest.

**Plotly**: It’s a graphing library for creating interactive graphs that can then be simply incorporated into web applications.

**Tidyr**: Data Scientists may use this R package to clean and arrange their data. When each variable represents a column, each row represents an observation, and each cell represents a single value, the data is called tidy.

**Dplyr**: It’s the go-to package for data manipulation and wrangling. It allows Data Frames in R to perform actions such as subsetting, summarising, rearranging, and joining data sets together.

**Caret**: The Caret Package is used for Predictive Modelling and stands for Classification and Regression Training. It improves Data Splitting, Pre-Processing, Feature Selection, Variable Importance Estimate, and other tasks while also offering a common interface to a lot of Machine Learning algorithms.

**Knitr**: Knitr is primarily used for creating reports in a number of file formats, including LaTeX, HTML, Markdown, LyX, AsciiDoc, and reStructuredText documents.

**Xtable**: When Data Scientists need to put an R project into a final document, it creates HTML or LaTeX code.
