A Complete Guide to Learn R

R Programming Technology is an open source programming language. Also, the R programming language is the latest cutting-edge tool. R Basics is the hottest trend. Moreover, the R command line interface (C.L.I) consists of a prompt, usually the > character.

History of R

John Chambers and colleagues developed R at Bell Laboratories. Basically, R programing language is an implementation of the S programming Language. Also combines with lexical scoping semantics inspired by Scheme. Although, R was named partly after the first names of two R programming language authors. Moreover, the project conceives in 1992, with an initial version released in 1995 and a stable beta version in 2000.

Install R Programming Language & R Studio

In this R tutorial, we are moving towards installations of R Programming and R Studio:

We have to follow three basic steps in the same order to run R programming language and R Studio on your system.

  • R Installation
  • Installation of R Studio
  • Install R Packages.

a. How to Install the R Programming Language?

In respect to the operating system we are using we have to follow the below-mentioned steps:

  • For Mac

First, we have to download the appropriate version of the .pkg file form the following link.

Further, open the downloaded .pkg file and Install R.

  • For Linux

For Ubuntu with Apt-get installed, execute sudo apt-get install r-base in terminal.

  • For Windows

Download the binary setup file for R from the following link.

Open the downloaded .exe file and Install R.

b. How to Install R Studio?

Choose the appropriate installer file for your operating system. Afterward, download it and then run it to install R-studio.

c. How to Install R Packages?

We require a particular package to be installed if we need to use R studio. Further, follow the instructions below:

Run R studio

Afterward, we need to click on the packages tab in the bottom-right section. Once, you complete this then click install. Thus, the dialog box will appear.

In the install packages dialog, write the package name you want to install the Packages field. And then click install. This will install the package you searched for. Either give you a list of matching package based on your package text.

Thus, the installation procedure for R Studio.

Why R Programming Language?

In this R Tutorial, following points describe reasons to learn R Programming.

  • We use R programming as a leading tool for machine learning, statistics, and data analysis. Objects, functions, and packages are easily created by R. As it is used anywhere. Also, it’s platform- independent and free. Thus, anyone can install it in any organization without purchasing a license. Moreover, it can be applied to all operating system.

  • R programming language is not only a statistic package. Also, R allows us to integrate with other languages (C, C++). Thus, you can easily interact with many data sources and statistical packages. As a result, the R programming language has a large growing community of users.

R For Business

R is best for business because it’s an open source. Also, it’s great for visualization. Moreover, the R programming language has far more capabilities as compared to earlier tools. Also, companies are using R programming as their platform and recruit trained users of R.

R vs Python: What Should Beginners Learn?

Let go of any doubts or confusion, make the right choice and then focus and thrive as a data scientist.

I currently lead a research group with data scientists who use both R and Python. I have been in this field for over 14 years. I have witnessed the growth of both languages over the years and there is now a thriving community behind both.

I did not have a straightforward journey and learned many things the hard way. However, you can avoid making the mistakes I made and lead a more focussed, more rewarding journey and reach your goals quicker than others.

Before I dive in, let’s get something out of the way. R and Python are just tools to do the same thing. Data Science. Neither of the tools is inherently better than the other. Both the tools have been evolving over years (and will likely continue to do so).

Therefore, the short answer on whether you should learn Python or R is: it depends.

The longer answer, if you can spare a few minutes, will help you focus on what really matters and avoid the most common mistakes most enthusiastic beginners aspiring to become expert data scientists make.

Complete Linear Regression in R | Machine Learning in R | R for Beginners

We are going to learn the introduction of machine learning and linear regression in R 4.0 programming. We will start with the introduction of machine learning then we will discuss the introduction of linear regression. I will also discuss types of linear regression and use cases of linear regression. there are two types of linear regression; simple linear regression and multiple linear regression. Use cases of linear regression are in house price prediction, stock price prediction, Twitter popularity prediction. I will thereafter show you how to analyze the Boston housing dataset. We will analyze dataset variables to understand the variable dependency for the linear regression model. I will show you the linear and non-linear regression models. Thereafter, I will show how you can improve the accuracy of a linear regression model.

Learn R the Right Way in 5 Steps — Learn Data Science at Dataquest

R is an increasingly popular programming language, particularly in the world of data analysis and data science. But learning R can be a frustrating challenge if you’re not sure how to approach it.

If you’ve struggled to learn R or another programming language in the past, you’re definitely not alone. And it’s not a failure on your part, or some inherent problem with the language. Usually, it’s the result of a mismatch between what’s motivating you to learn and how you’re actually learning.

This mismatch causes big problems when you’re learning any programming language, because it takes you straight to a place we like to call the cliff of boring.

learn r for data science - the cliff of boring

What is the cliff of boring? It’s the mountain of boring coding syntax and dry practice problems you’re generally asked to work through before you can get to the good stuff — the stuff you actually want to do.

Nobody signs up to learn a programming language because they love syntax. Yet many learning resources, from textbooks to online courses, are written with the idea that students need to master all of the key areas of R syntax before they can do any real work with it.

That’s where new learners tend to drop off in droves. You get excited about learning a programming language because you want to do something with it, and but then you’re immediately led to this huge wall of complicated, boring stuff that’s between you and what you actually want to be doing. It’s no surprise that lots of students give up or drop off at points along their climb up this “cliff.”

There’s no way around learning syntax, in R or any other programming language. But there is a way to avoid the cliff of boring.

It’s a shame that so many students drop off at the cliff, because R is absolutely worth learning! In fact, R has some big advantages over other language for anyone who’s interested in learning data science:

  • The R tidyverse ecosystem makes all sorts of everyday data science tasks very straightforward.
  • Data visualization in R can be both simple and very powerful.
  • R was built to perform statistical computing.
  • The online R community is one of the friendliest and most inclusive of all programming communities.
  • The RStudio integrated development environment (IDE) is a powerful tool for programming with R because all of your code, results, and visualizations are together in one place. With RStudio Cloud you can program in R using RStudio using your web browser.

Google Reveals "What is being Transferred” in Transfer Learning

Recently, researchers from Google proposed the solution of a very fundamental question in the machine learning community — What is being transferred in Transfer Learning? They explained various tools and analyses to address the fundamental question.

The ability to transfer the domain knowledge of one machine in which it is trained on to another where the data is usually scarce is one of the desired capabilities for machines. Researchers around the globe have been using transfer learning in various deep learning applications, including object detection, image classification, medical imaging tasks, among others.
