This is a basic R programming course for beginners. Just follow along with me and type in the code twice. You will naturally become a beginner!
Basic knowledge of programming
Basic knowledge of R programming
Basic grammar of coding and algorithmic thinking
R programming, the easiest and most natural way!
Are you new to coding? Does programming feel unfamiliar and distant?
This course is for those who are learning coding for the first time .
The class is conducted under the assumption that the students are completely incapable of coding.
Used for data analysis, statistical simulation, text mining, etc.
R is a very intuitive, easy-to-use, and versatile language.
Expand your programming skills with a low barrier to entry!
R is a very intuitive and easy to understand language.
It's a very suitable language for beginners who are learning programming for the first time.
All programming languages share structurally similar characteristics. While it might take a beginner coding 10 hours to learn Python, someone familiar with R would only need 5 hours to learn Python. In other words, because programming languages share similar characteristics, learning one will require significantly less time to learn two.
We'll help you get started with coding using R, an easy-to-use and useful programming language.
If you've ever wanted to learn programming but weren't sure which language to learn, start with this beginner's course!
1️⃣ R Programming for Beginners
I've structured this course so that even those who have never coded before can easily follow along. I believe the easy-to-understand R language will help break down the barrier to entry to programming. It's suitable for those who need R immediately, as well as those who want to learn coding. You don't have to try too hard to understand. Let's learn programming skills by following along with me. 😊
2️⃣ 100% live coding classes
This course is 100% live coding. Simply watching the lectures will never improve your skills. It's crucial to practice coding by following my code and gaining a sense of real-world coding. Just write code with me twice and you'll see a noticeable improvement in your skills. 💪
Various programming constructs, such as the if statement, commonly used in Excel, are similarly structured in all programming languages. Learn about commonly used programming constructs such as if, if else, for, and while.
99% of data used in R is comprised of Vectors, Dataframes, and Lists. A thorough understanding of these three objects will ensure seamless data handling in R. This article covers the characteristics, differences, and access methods of these three objects in detail.
Saving and managing data is crucial. We'll learn how to save and retrieve data we've created or processed in Excel format, as well as how to safely save and retrieve it without data loss. We'll also learn how to automatically create new folders using loops, save and manage files, and automatically retrieve only the files we want from numerous folders and files.
You'll learn about various functions that help you process data. We'll cover functions that sort values by size (sort, order), string manipulation functions (stringr, gsub, %in%), and techniques for accessing data objects and quickly applying functions (apply, sapply, tapply, lapply). You'll also learn how to create and use your own functions.

주로 연구하는 분야는 데이터 사이언스, 강화학습, 딥러닝 입니다.
크롤링과 텍스트마이닝은 현재는 취미로 하고있습니다 :)
크롤링을 이용해서 인기있는 커뮤니티 글만 수집해서 보여주는 마롱이라는 앱을 개발하였고
전국의 맛집리스트와 블로그를 수집해서 맛집 추천 앱도 만들었었죠 :) (시원하게 말아먹..)
지금은 인공지능을 연구하는 박사과정생입니다.
