Because of the growing demand for R developers, more people are interested in learning the language. However, many people find learning R challenging due to its complexity, and most online R courses are paid—fortunately, platforms like YouTube offer free courses for learning R visually.

Before we get started with the list of the top 10 YouTube courses for learning R, let us take a moment to review the R language in detail.

### R Language Overview

R is a computer programming language that was created by the R Core Team and was first used in August 1993. The R version, which enables expert programmers and academic statisticians to conduct intricate statistical analysis on large amounts of data and present the findings in various visual formats, was first made available in 1995. The name R is said to have come from the first letters of the names of the key developers (Ross Ihaka and Robert Gentleman).

Following the success of the statistical analysis application of this language, it was adopted as a programming language for data visualization projects. This makes it the ideal programming language for data mining, machine learning, statistical computing, bioinformatics, and data analysis.

Every programming language has its weaknesses; the R language is no exception. It has been faulted for generating slow analyses when applied to large data sets. One CPU can only be used at a time in the basic open-source version of the language due to its use of single-threaded processing. These limitations have decreased the R language’s applicability in big data applications. Rather than utilizing R for production tasks, numerous enterprise users employ it for exploratory and investigative purposes. After performing complex analyses on sample data using R and finding a significant correlation or cluster in the data, data scientists will use enterprise-scale tools to implement their findings.

There is some level of integration between analytics software and the R language offered by vendors such as IBM, Microsoft, Oracle, SAS Institute, TIBCO, and Tableau. Popular open-source big data platforms like Spark and Hadoop also have R packages available for them

### R language: Features and Environment

When coding with the R language, developers can effortlessly implement new functionalities when they define new functions. Users can extract a single variable, join multiple data files into a single document, and run a regression on the resultant data set. Discrete operations can be combined into a single, reusable function within the environment.

The R programming language supports functions for a variety of applications, including classical statistics, linear and non-linear modeling, classifications, and clustering. It also incorporates a wide range of libraries, a sizable and vibrant user base, and integration capabilities with both C and C++. This programming language offers a large number of operators and tools for data analysis, effective data handling, and storage.

One of R’s best qualities is that it can be used to create neural network packages for artificial intelligence (AI), and it is a platform-independent language that runs on all computers, including Windows, Mac, UNIX, and Linux. Developers can read data, add it to the workspace, issue commands, and see the outcomes through the conventional command-line interface.

Another common feature in the R programming environment is looping functions. These features enable users to carry out specific tasks, like repeatedly extracting samples from a larger data set. Its extensive feature set and free download from the Free Software Foundation under the GNU general public license have contributed to its enduring appeal in academic environments. The R language is robust and can be run on Windows, Linux, MacOS, and UNIX operating systems.
