What is R programming language ?
What is R programming language?
So let’s, first understand the meaning of programming language R ?
This language was developed by Mr Ross Ihaka and Mr Robert Gentleman, who were associated with Department of Statistics with in UoA (University of Auckland). They initial release of R version in August 1993 which allowed statisticians’ students and others users to learn with programming skills which ultimately help in analyzing statistical on complex data analysis and graphical representation. Both the developer kept this language name on their first letter of their name “R”, R-oss and R-obert.
R language includes functioning to support various statistical methods for example
- Linear Modeling Method,
- Non-Linear Modeling Method,
- Classifications Method,
- Classical Statistics Method,
- Clustering Method and much more.
This language is more popular among the students cause of its robust features and due to its open source software version. It is free to down-load in terms of Free Software Foundation (FSF) as general public license. This language support and can run on all type of popular operating systems Windows, mac OS & Linux.
R allowed users to use their own syntax, functions and code. In the R environment allows users to combine their individual needs, which may include adding different data set files into a one file of document. Its also allows users to pull out single variable from the data set and by running a regression, single function/code can be used multiple time in R environment.
Present world, the demand of the R language has gradually extend from students to business setups, institutes are also giving training to their students of data analysts, students of who trained on R more favorable in continue using this language rather than pick up a new software or tool with which they have not taken any experienced.
R has built with the standard command-line interface.
Users control this to read data and load it to the language interface, specify commands and achieve desired results.
R environments can be use after thru commands for Arithmetical Operators, that includes +, -, / and *, to more complex functions that act upon the Linear Regressions and more advance calculations. The looping functions are also trendy in the R programming environment.
All the above functions / command allow users to repeat same action without many hassles and in smoother manner. With the loop function, users can pull out the samples from a bigger data set basis the time line set by the user to specific task.
Like every language R also have few Advantage and Dis-advantage in it.

It is Gudtoknow that now R language has ability to perform all statistical task,
R is almost unique among all other programming languages available for Data Analyst it is meant for all level of Data Miners.
WE CAN ALSO SAY DATA IS DEEPLY INSERTED IN BLOOD OF THIS LANGUAGE.
