Data Analysis

Network Analysis with R

Learn how to draw networks using R. Rather than drawing the network itself, we focus on building the shape of the data that will go into the network and how to draw the network nicely.

🙆🏻‍♀ Learn how to draw networks using R. Rather than drawing the network itself, we focus on building the shape of the data that will go into the network and how to draw the network beautifully.🙆🏻‍♂



How to draw a pretty network with R/Network visualization using Gephi


🗒 Course Introduction

It is not difficult at all to draw a network using the network package. Just search for igraph in r on Google, copy + paste + run the example code that appears. However, it is not easy to draw a network using the data I have. This is because it is not easy to create data to enter the network function. In this lecture, you will learn how to preprocess your data into network data and draw a network using various R language functions and draw it nicely. The contents covered in this lecture are as follows.

🌈 Introducing Igaph

Introducing igraph, the most representative network package in R.

🌈 Network data preprocessing

In this lecture, we will draw a network for the purpose of extracting related words to the top keywords of news articles.

Preprocess text data to be fed into the network.

🌈 Drawing a network

Let's visualize the network using igraph and ggnetwork. We will also visualize the interaction network plot using visnetwork.

Visualization using Igraph

Visualization using ggnetwork

Visualization using visnetwork

🌈 Network visualization using Gephi

Let's visualize the network using gephi, a network-specific visualization software.

🙋🏻‍♂️ Expected questions related to the lecture

Q. Can I listen without knowing R at all?
A. It will be easier to listen if you have basic knowledge of R and basic knowledge of text mining. ㅠㅠ. I recommend that you take and listen to the R programming basics lecture (free) and text mining lecture that I uploaded.

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.
