What is R programming and 10 reasons you should learn R
What is R?
R is a programming language and software environment for statistical computing and graphics supported by the R Foundation for Statistical Computing. It is a GNU project which is similar toÃ‚Â the S language and environment which was developed at Bell Laboratories by John Chambers and colleagues. R can be considered as a different implementation of S.
R is available as Free Software under the terms of the Free Software FoundationÃ¢Â€Â™s GNU General Public LicenseÃ‚Â in source code form. It compiles and runs on a wide variety of UNIX platforms and similar systems, Windows andÃ‚Â MacOS.
The R environment -
R is an integrated suite of software facilities for data manipulation, calculation and graphical display. It includes
- an effective data handling and storage facility,
- a suite of operators for calculations on arrays, in particular matrices,
- a large, coherent, integrated collection of intermediate tools for data analysis,
- graphical facilities for data analysis and display either on-screen or on hardcopy, and
- a well-developed, simple and effective programming language which includes conditionals, loops, user-defined recursive functions and inputÃ‚Â and output facilities.
Reasons to learn R -
1. R is freely available - Unlike SAS or Matlab, you can freely Ã¢Â€Âœinstall, use, update, clone, modify, redistribute, and even resellÃ¢Â€Â R.
2. R has widespread acclaim - GivenÃ‚Â all these benefits, itÃ¢Â€Â™s not surprising that R is gaining wide-spread acclaim Ã¢Â€Â“ it is estimated that it has about 2 million users, and a recent poll suggests that it is the most popular language in data science.
3. R is a heavy-duty language - As a powerful scripting language, R will help you handle large, complex data sets. It is a great programming language to compute Big Data.Ã‚Â R is also the best language to use for heavy, resource intensive simulations. Furthermore, R can be used on high performance computer clusters which manage the processing capacity of huge numbers of processors.
4. R leads innovations in statistics - Many new developments in statistics first appear as R packages. This is because R is highly flexible and evolved.
5. Language integrate - Need to run statistical calculations in your software application?? Deploy R! ItÃ‚Â integrates with many programming languages like Java, Ruby, C++, Python
6. R is loved by publishers - RÃ‚Â is a language that integrates easily with document publishing. By integrating smoothly with the LaTeX document publishing system, statistical output and graphics from R can be embedded in word-processing documents.
7. Reusable libraries - R hasÃ‚Â 2000+ free librariesÃ‚Â to use in areas of finance, natural language processing, cluster analysis, optimization, prediction, high performance computing etc.
8. No Windows, No Doors Ã¢Â€Â“ R runs on all the platforms. Just name it and you got it!! Windows PC, Mac, Linux.
9. Used by many popular companies - Leading firms like NY Times, Google, Facebook, Bank of America, Pfizer, Merck are all using R.
10. IT demand - Want the coolest job in 2017?? Learn Statistics.Ã‚Â It is the future. Data Scientists will be the sexy job in 2018.Ã‚Â
