Thank you for the great lecture.

What you will gain after the course

  • Graphs using basic functions

  • ggplot2 Basics

  • Basic Graphs (Scatter/Line/Bar)

Learn R data visualization properly!
Come join us at [R for R] ✨

The data I will be handling,
Can't we see it at a glance?

When analyzing data, how can we see the characteristics of the data we need to deal with at a glance? How can we find insights from the data more easily and better? Listed numbers or tables have their limitations. That is why data visualization is important.

This lecture!

지지플롯2

The most popular R data visualization library,
Let's draw a graph with ggplot2 .
Scatter plots, line graphs, bar graphs, etc.
Learn how to present data effectively.

If you have some basic knowledge of R and can freely visualize data using basic R functions and the ggplot2 package, you will be very efficient .

Only for this lecture
Check out the benefits.

No more simple spoon-fed education, get theory and practice at the same time.

  • A total of 24 classes are divided into theory , practice , and quizzes .
  • It is dangerous if you only feel like you have learned something without improving your skills. 🙅‍♂️
  • Therefore, in addition to quizzes given throughout the class, we also provide hands-on practice so that you can input code directly .

There are quizzes like this for each class. 😉

Check every detail carefully!

  • Learn thoroughly what you need to know about real-world data visualization .
Including the necessary details such as errors, help inquiries, etc.
I'll introduce the main functions in this summary!

Easy to understand with real-life examples!

  • We've even done a simple project to visualize COVID-19 vaccine data directly on a map.

Spread the COVID vaccination data on a map🗺️.

Expected Questions Q&A

Q. I don't know anything about R. Is that okay?

It's not okay at all. If you haven't taken [R for R] Basics, you should be able to install and load packages/input/output files/filter data frames to be able to take the course without difficulty.

Q. What is ggplot2? Why learn it?

There are many functions in R that can draw graphs, but they are too crude and difficult to handle, so I don't use them often. I will focus on learning the ggplot2 package, which helps me draw more attractive and pretty graphs more conveniently.

Q. Even if I learn this, won't I still be able to draw graphs with the data I have?

You will be able to draw graphs that can be inserted into papers on your own.

Q. How well will I do if I study and understand everything that comes out here?

It will be very helpful because it goes beyond just introducing various functions and provides hands-on practice using various data.
