An open-source programming language, R is used as a statistical software and data analysis tool. Data Science with R course is a popular and top choice of various statisticians and data scientists. Data science is a very popular field in present times as there is a growing need for analyzing and constructing insights from data.
R is a language that provides an intensive environment for individuals to research, process, transform, and even visualize information. This is a powerful language used excessively in data analysis and statistical computing. R language has gone through a rough journey from the rudimentary text editor to interactive R Studio and, recently, Jupyter notebooks and has engaged with various data science communities.
R is an implementation of the more fundamental S programming language. The main advantage of this language is that it is free software. R is an open-source language that is accessible as free software and is also compatible with different systems and platforms. It is flexible, powerful, has an amazing ecosystem for developers, and has a wide range of packages mainly for data access, data cleaning, performing analysis, and creating reports.
Some valuable things to know about R in data science:
- R is an open-source software: this is free and even adaptable as it is open-source software. It is an open interface that allows one to integrate with other applications. It has high-quality standards, and various people use and iterate on it.
- R is used for data analysis: data science with R is used for handling, storing, and analyzing data. R is used for data analysis and statistical modeling.
- R is a programming language: this is a programming language that provides objects, operators, and functions that allow one to explore, model, and also visualize data.
- R is community: R project contributors involve people who have suggested different improvements, have checked on bugs and created add-on packages.
- R provides an environment for statistical analysis: R has different statistical and graphical capabilities. It is used for classification, clustering, statistical tests, and linear and non-linear modeling.

How is R used in Data Science?
R for data science mainly focuses on language for statistical and even graphical uses. As soon as you learn this language, it can be used for performing statistical analyses and even developing data visualization. R’s statistical functions make it easy to clean, import, and even analyze data. R has now one of the richest ecosystems for performing data analysis. There are around 12000 packages which are available in CRAN, which is an open-source repository. This makes it possible to find a library for the analysis one wants to perform. Rich variety makes R one of the best choices for statistical analysis, especially for specialized analytical work. R has advanced tools for communicating the results.
Features of R-data science:
Let us have a glimpse of some of the features of R-data science uses:
- R provides extensive support for statistical modeling.
- It is a suitable tool for numerous data science uses as it provides aesthetic visualization tools.
- R is utilized in the data science app for ETL, and it provides an interface for different databases such as SQL and spreadsheets.
- R provides different packages for data wrangling.
- With R, data scientists apply ML algorithms to collect information about future events.
Why learn R?
Let’s take a look at the benefits of using R are below:
- Style of coding is easy
- It is open-source, and there is no requirement to pay any subscription charges
- Community support is overwhelming as there are various forums to help one.
- Attain a high-performance computing experience
- It is a highly sought skill by analytics and data science companies.

Which are the essentials of R programming?
One must understand and even practice the essentials of a programming language as this is a building block of R programming knowledge. R has five basic or atomic classes of objects. These 5 basic classes of objects include character, numeric, integer, complex, and logical. These classes also have attributes. Objects even have the following attributes such as name, dimension name, dimensions, class, and length.
Important packages of R for data science:
Let us have a look at the important packages:
- Ggplot2: R is famous for the visualization library ggplot 2. This provides an aesthetic set of graphics that are also interactive. Ggplot2 comes with different extensions, which increase the usability and experience too.
- Tidyr: this is an R package that allows one to clean and even organize the data. This treats the data in properties i.e., every column is treated as a variable, and every row is an observation. Three different functions are used for organizing the data into rows and columns.
- Dplyr: this allows engineers to organize, manage and wrangle data. It uses declarative syntax that is easy to remember. Dplyr facilitates different operations.
Is R difficult?
R is a programming language, and it is a difficult language to master. This language was confusing and not as structured as other programming tools. However, Data manipulation has become trivial and intuitive with R. as it has the best algorithm for Data Science. R has a package that performs Xgboost and is one of the best algorithms for competition. It can easily communicate with other languages. The world of big data accessible to R. R has evolved and allowed parallelizing to speed up computation.
There is no prerequisite to taking data science with an R course. However, knowledge of any language and core mathematics serve as an added advantage. Professionals with a technical background and prior detail in data science tend to progress faster in learning data science. Various companies are using data science to gain insights from customer data and to make informed decisions. This even involves a range of processing from collecting data, cleaning, and even processing the data visualization.
R is a great language for exploring and investigating the data. Deep analysis such as clustering, correlation, and data reduction is done with R. It is important as it doesn’t require good feature engineering and model. With the features R offers, it is an obvious choice for data science and business intelligence.
