R is a high-level, compiled, computer programming language. It has the power to manipulate and perform almost anything, giving you the power to create advanced algorithms, performing functions such as linear regression, machine learning, and interactive graphics.
Making use of R is similar to using a programming language in another language. You first learn the syntax and basic operations of R, then you can move on to more complex topics.
This article will go through some tips on how to learn R for those looking to take their software development skills up a notch.
Find a good book on R
While there are many books that teach you how to program in R, there are also a lot of tools and resources available to you. You can go online, read books in the comfort of your own home, or even get into person and learn from a book or course.
The best way to learn how to use a book in the beginning is to just pick one! There are plenty of great books on the market that cover all the basic skills for R.
Some of the best books on programming in R include: Programming with Graphics (which covers creating and manipulating graphics), Statistical Computing (which covers statistical analysis and estimation), and Machine Learning (which covers strategies for categorizing data).
Buy a video course on R
There are several best-of-the-best-video-courses on R, so you do not need to spend a lot of time searching for the best one. However, if you are new to R programming or just want to learn it, taking a video course is the best option.
It is very interactive and you can follow the steps how to learn R language in the course. You can also try joining online courses offered by different professionals like data scientists or programmers.
They offer their courses on YouTube, Google Drive, and Amazon Video. Choose one that matches your skills and watch them daily to learn some fundamentals of R programming language.
Download demo data and try out programs
Even if you are not good at programing or Data Analysis, you can still try to learn the language by downloading examples of R programs. There are many online, as well as in your textbooks (if they have some).
These examples are great to try out too- they are designed to be easy to understand and put into practice. Some of them even integrate with the web!
Just download and run them!
These programs are great for practicing your code reading and data plotting skills. Once you get the hang of it, you can upload your completed programs to the internet and share them with the world!
They also give you a chance to take some feedback and make them more clear/ simpler/ longer so you can keep improving.
Practice making charts and graphs
There are several ways to learn how to make charts and graphs in R. We will look at two popular methods here. The first is the Charts and Graphs in R course from Stanford University. This course is designed for first-time learners, but also includes advanced features.
The second way to learn how to make charts and graphs in R is by taking the Interactive Charting Course from Stanford University. This course does not cover advanced features, but does include a step by step tutorial that helps you get started.
Either way, both of these learning approaches focus on using data to create visual representations of information.
Learn basic programming concepts
When you start to learn R, the first thing you’re going to need to learn is how to program. In this article, we will explain how to program in R using basic concepts.
Assemble a collection of data that you want to manipulate. For example, you can have an inventory of goods at your store, or a map of your neighborhood.
Figure out how to use R for data manipulation and analysis. For example, you can take the inventory of goods in your store, and count the number of items present. You could do a linear regression analysis on this variable to see if the number of items present has changed over time.
When doing analytics in general, it is important to understand how R operates.
Read the manual
Without a good grasp of R, you will not be able to run R code or create R reports. There are many books on the market that teach you how to use and work with R.
Many of these books are geared for more advanced users, so if you are new to R, do not expect to just start learning codes off the internet and on your desktop. You will need to study the manual and pick up tips and tricks from them until you understand all the features of R.
It is important to read through the features of R because some may be restricted or unavailable in an introductory course. For example, being able to save data in and out of R files is a feature that must be built into an introduction to give students access to this data.
Without knowing how to use this data in an appropriate way, students would not learn much about R programming language.
Take an online course
There are many free courses that teach you the basics of R. You can find them at course-online-courses.com or you can create your own course using the very basic features offered by R.
Many of these courses are designed for beginning code users, so it is easy to start learning. Most have you finish in a few weeks!
Most have you finish in about a week, and in the end, you will have a very good understanding of what R is doing and why it works.
In fact, this is one reason why so many people find R so powerful — it takes you step by step into understanding what data exploration techniques are doing and why they work.
Create your own r/data scrape project
In this article, we will show you how to create your own data scrape project using the r/data API. This article will also help you create your own data scrape project!
Creating your own data scrape project allows you to control how you use the r/data API. You can for example choose to only get tweets with a certain hashtag, or only tweets from a certain country.
To make this step-by-step guide easier to follow, we will also show you how to create your own data scrape project.
