R is a popular programing language that used for Data Analysis and statistics. Its a free tool that is widely used by Data Scientist and Analytics. The focus of this programming language is to operate all kind of data operations end to end, which make it different from other programming languages. It has many functions and libraries. The R language is provides a wide variety of statistical and graphical techniques. R is available for free on its official website which can be available for all kinds of different platforms i.e. UNIX/LINUX, WINDOWS and MAC OS.

R is developed by Ross Ihakes and Robert Gentleman in 1993. it includes statstical and graphical technique as well as it perform machine-learning algorithms, regration techniques, time series, statistical inference and so on. Most of R libraries are written in R, but for heavy computational tasks C, C++ & Fortran codes are preferred.

In Short R is

Complete statistical language
Excellent graphical outputs
Cross-platform compatibility
Can be connects with other languages
has vast community
2000+ free libraries
easy to learn
open source
latest cutting edge technology
gateway to incrative career
used in almost every industry

Carrier in R

“R has been a Game Changer in the Analytics Industry.”

The field of data science has been exploded n the best two decades and shows no sign of stopping.

Many big or small business and companies wish to make use of the insight gained through the big data.

You can get millions of job opening for R programming world. Jobs portals like LinkedIn, Glass-door, Indeed, Naukri, Times, Monster and so on, all have thousands of Job listing.

Various Sectors for R Jobs:

Financial Sectors

Various companies using R:

Installation:

You can install R for your UNIX/Windows or MAC from their official website:

https://cran.r-project.org/

as well as you can download R studio from below site:

“R studio is IDE for R technology”

R Window

The command line prompt, i.e. the > , is an invitation to start typing in your commands. For example, type 2+2

and press the Enter key. Here is what appears on the screen:

> 2+2

[1] 4

Here the result is 4. The [1] says, a little strangely, “first requested element will follow”. Here, there is just one

element. The > indicates that R is ready for another command.

Drawbacks of R:

Essentially based on 40-year-old technology
Functionality is based on consumer demand and user contributions
Objects must generally be stored in physical memory
Your data must fit within the contiguous RAM of your hardware
True of other software such as scikit-learn, WEKA, and TMVA
There have been advancements to deal with this, including:
Interfaces to Spark and Hadoop
Packages ff and bigmemory
File-backed data objects
Big RAM is eating Big Data!
You can now get 2 TB X1 instances on Amazon EC2
Google and Microsoft also offer instances with large RAM
Trend driven by companies who increasingly are replacing local hardware with cloud computing and need massive compute resources

That's all about R technology introduction hope you understand the R intro and its useful for you.

We will get back to you with more tutorials of R programming which you learn and apply to your professional life as well.
