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.

Advantage of R Language:
  • Open source language and free to download,
  • Offers complex data analytics capabilities
  • Active group of communities and users online for support.
  • 25 years old quite mature language.
  • Multiple add-on packages for enhancing the basic functionality
  • users to graphical data representation,
  • Integration with external database systems,
  • Geographically mapping of data and
  • It allows user to use advance level statistical functions.
  • Simplification of coding experience with R Studio

It has a much bigger library of statistical packages – Doing specialized statistical work. R has multiple packages with wide range of statistical tasks by using the CRAN task view.

In the toto we can say R packages also cover all from Psychometrics to the Genetics to Finance.

Disadvantage of R language
  • Utilizes only single-threaded processing system in basic open source version
  • Utilization of one CPU at a time – Slow analyses delivery for a larger data sets
  • Memory based application.
  • All data objects stored only in computers RAM during a given session which is also limit the size of data R is able to work on at one time.
Final word on R

Now days various software service providers have also added their support for R language into their offerings, allowing R to gain a stronger foot prints in the modern Data Analyst structure and big data dominion.

The service providers those offering support to R functions included big giants like IBM,

Microsoft, Oracle, SAS Institute, TIBCO and Tableau. Others small software players are also included R language integration in between their analytics software and the R programming language. There are also R packages available for popular open source big data platforms, including Hadoop and Spark.

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.

Journey from 1G to 5G – How The Internet Has Changed The World

The Internet has completely revolutionized the way we communicate. Whatever we need to do we now have the option of doing it online; from ordering a takeaway, to carrying out our weekly shop, chatting with a friend, or booking our next holiday, the Internet gives us access to a wealth of knowledge and communication tools that allow us to interact with others worldwide without even leaving the house.

Perhaps the biggest impact that the internet has had on our lives today is on social relationships. All barriers to communication have been removed; no longer are we constrained by space and time, and more recent developments in instant, mobile communication also mean that we are not tied to a specific device. We can log on to mobile phones and tablets and access information stored remotely in a ‘cloud’. This has resulted in people staying online, wherever they are, at any time.

Of course, the Internet has its drawbacks and presents new challenges to privacy and security. However, our world is now one that is networked, and connected by new technologies, bridging gaps between cultures and societies and significantly enhancing globalization.

In just a few, short years the Internet has changed the world and the ways in which we conduct our daily lives. No longer do we need to buy a newspaper to catch up with current events, we can now watch situations unfold online, in real time, making the introduction of the Internet one of the greatest achievements of mankind.

How to Change Screen Resolution Windows 10

Posted on by

The subject I’m about to talk to you is one of those that takes for granted everyone knows perfectly, but in reality it is not so, especially when you try for the first time a new operating system. The question of how to change the screen resolution is, in fact, one of the most frequently asked questions for those who find themselves for the first time in front of a new virtual work environment.

This is the reason why today I want to tackle the topic with you and make a brief overview of the procedures to set the screen resolution on all major computer operating system: Windows.

Windows 10 is installed on your computer and you want to know how to proceed to change screen resolution? So the first thing you need to do is to go to the desktop and right-click on an empty spot. Then select the Screen Settings item from the menu that is shown to you.

 

In the window that opens, presses on the item Advanced screen settings, identify the item Resolution and then use the appropriate menu below to set the resolution that you think may do most for you. Then click on the Apply button and then on that Keep changes to apply and keep the changes made.

If instead you want to find out how to change screen resolution just because you would like to be able to change the font size of all the items displayed on the desktop (maybe to read them better!), The steps you need to take are different from those seen above.

To do this, you must right-click on an empty spot on the desk and select the Screen Settings item   from the menu that appears and then you must use the adjustment bar located under the Change text size, app and other items to set the level of zoom that you prefer. To apply the changes in some apps, you’ll need to log out of your account and sign in again to Windows.

If instead you want to go to act only on the size of the characters without altering the degree of zoom of all other elements displayed on the screen, right-click in an empty spot on the desktop and select the Screen Settings item   from the menu that appears.

*****Special Attentions******

Changing screen resolution can only take place when the computer’s video card is well recognized by the system, this means that if the operation fails you (the available resolutions are very few and all very low) and you use Windows or Ubuntu, you need to install / enable updated drivers to solve the problem.

To Do This:

  • Stay on the same page and scroll: under Apply you will find the Related Settings section, here select Display adapter properties to open a new window.
  • On the first page, under the Adapter option you will find your graphic card: click on Properties.
  • In the new window that opened, at the top, select Driver.
  • Then choose Update Driver.
  • Update Driver and Restart your pc.

60 SECONDS ON INTERNET IN 2018

What Happens in an Internet Minute in 2018 ?

Posted on by

In your day to day life, a minute might not seem like much.

But when it comes to the huge scale of the online world, a minute of time goes much beyond than you ever could have imagined. That’s because the internet has a degree of scale that our linear human brains are not familiar to operating on.

60 SECONDS ON INTERNET IN 2018

This inforgraphic is from Lori Lewis and Chadd Callahan of Cumulus Media, and it shows the activity taking place on various platforms such as Facebook or Google in each 60 second span.

It really helps put an internet minute in perspective.

WAIT A MINUTE, PLEASE !!

The numbers for these services are so HUGE that they can only be shown using the 60 second time scale.

Any bigger, and our brains can’t even process these massive quantities in any useful capacity. Here are some of the key numbers scaled to a monthly basis, for fun:

42,033,600,000 Facebook logins
159,840,000,000 Google searches
1,641,600,000,000 WhatsApp messages sent
8,078,400,000,000 emails sent
On an annualized basis, the data becomes even more ridiculous, with something close to 100 trillion emails sent. (No wonder it’s so hard to get to inbox zero!)
