Introduction to R

Online event

It has been two years since Quarto became the most popular reproducible publication tool in data science and the R community. However, Quarto is so much more than just a publication tool! I started using it in late 2022, and it has helped me become more organized, productive and connected with people in the data science community.
In this talk, I will not focus on the technical aspects of 'how' to use this tool. In the first part of the talk, I would like to report the latest news and trends seen in the useR conference and Posit conf, the two biggest global R events. In the second part, I will share my own experience in using Quarto for my career: from learning new skills, collaborating with co-workers, teaching university courses networking and building a community (CAMIS collaboration). It is a powerful tool to share your work, and make new connections - both for work and for fun! I hope this talk will provide you with some new ideas on how to use this fantastic technology to fulfil your goals.

## AI 시대 Shiny 의 미래

### Tidymodel의 기본 철학: Chatgpt시대의 한계와 가능성을 중심으로

* 제목: “Tidymodel의 기본 철학: Chatgpt시대의 한계와 가능성을 중심으로”
* English Title: “The Core Philosophy of Tidymodels - Challenges and Opportunities in the ChatGPT Landscape”
* 발표자: 공병규(유타대 아시아캠퍼스)
* 발표요약: Tidymodel은 기존에 파편화되어있던 머신러닝 코드를 tidyverse의 프로그래밍 철학에 따라 한데 묶은 혁신적인 R기반의 머신러닝 종합 패키지이다. 이번 발표에서는 최초 출시 이래로 줄곧 사랑받아온 tidymodels의 기본 철학을 기존 다른 R 패키지와 파이썬 머신러닝 패키지들의 문법과 비교하는 방식으로 다시 조망한다. 그리고 최근 새로운 프로그래밍 플랫폼으로 널리 자리잡은 chatgpt 시대에 이러한 tidymodel이 어떠한 의미와 한계를 가지는지 간단히 논의하고자 한다.

### Shiny(+서버)를 활용한 데이터 시각화와 실시간 웹 애플리케이션 개발 및 배포 전략 - 언론데이터 사례

* 제목: Shiny(+서버)를 활용한 데이터 시각화와 실시간 웹 애플리케이션 개발 및 배포 전략 - 언론데이터 사례
* English Title: Data Visualization and Real-time Web Application Development and Deployment Strategy Using Shiny (+ Server) - A Case Study with Media Data
* 발표자: 신종화 (조원씨앤아이, CRO)
* 발표요약: 리눅스 컨테이너(lxd)를 이용하여 내부망에 다수의 프로젝트형 RStudio/Shiny 서버를 구축하고, 웹 기반 데이터 시각화 및 요약 서비스 구축 사례를 언론데이터를 활용하여 시연한다.

### 생산성 향상을 위한 나만의 R 패키지 빌드

* 제목: “생산성 향상을 위한 나만의 R 패키지 빌드”
* English Title: “Building Your Own R Package for Productivity Enhancement”
* 발표자: 주석훈(SCOR 재보험)
* 발표요약: 개인의 생산성 향상을 위해 ‘빠르게’ R 패키지를 개발하고 배포하는 방법을 공유한다. 주로 사용하는 코드 및 노하우를 녹인 패키지가 개발되면 해당 패키지를 활용하여 자신의 업무에 도움이 되는 다양한 패키지를 연계 개발할 수 있게 된다.

### 인공지능을 활용한 가상 캐릭터의 특성 기반 마약 의심 SNS 포스팅 탐지 솔루션

* 제목: 인공지능을 활용한 가상 캐릭터의 특성 기반 마약 의심 SNS 포스팅 탐지 솔루션
* English Title: “AI-Powered Solution for Detecting Suspected Drug-Related SNS Posts Based on Virtual Character Traits”
* 발표자: 안상선 (엠로보)
* 발표요약: 대한민국은 마약류 사범은 2021년 현재 1만6163명으로, UN기준으로 인구 10만명당 마약류사범이 20명 미만(약 1만여명)인 경우 부여하는 마약청정국의 지위를 사실상 잃은 상태임 - 특히 마약을 거래하는 플랫폼인 텔레그램, 결제에 쓰이는 암호화폐는 익명성을 특징 으로 하고 있어 단속 및 적발이 어려운데, 이 같은 취약점을 노리고 최근 인스타그램및 X(트위터)로 마약 판매 포스팅이 폭증하고 있음
* 이에 인공지능을 이용해서 마약판매 의심 포스팅을 쉽고 빠르게 탐지하는 솔루션을 제안함.

서울 R 미트업 (9월) - Seoul R Meetup September 2024

교보타워

Join us for the Season opener at CalgaryR. Are you curious about the language, are you a seasoned data modeller or statistician, or anything in between? This is an excuse to mingle with like-minded people, mentor someone who is just starting, or listen to a talk and share in some lively discussions.

There will be two talks, the first one is called "**It's a feature, not a bug! Coercion, recycling and sub-setting**". We will be digging deep to uncover some of R's superpowers and pillars of the core R syntax for expressive and powerful data manipulation and mathematics.

The second talk is "**Data Science Proof of Concept Design: Applications in Oil and Gas**". Dr. Muir will show the process for managing and executing data science-based Proof of Concept projects in Oil and Gas. This concentrates on the initial understanding of the problem and requirements from the client to develop the analytics, predictive modelling and forecasting. Once defined and architected, solutions pass over to the implementation team.
The impact of the following examples of projects is in the 10s of millions per year. These projects took from 3-8 weeks

* Increased solvent recovery from oil sands tailings, 1st and 2nd stages
* Steam heat allocation in oil sands extraction and processing plant
* Soft sensor design to generate near real-time distillation curves (ASTM D86), octane rating, cloud point, etc., of crude and processed oil
* Estimated Ultimate Recovery (EUR) of unconventional assets: analysis and optimization

CalgaryR: Season Opener

(Room 440A and D) Taylor Family Digital Library, University of Calgary 

**Speech #1:**
**Anna Dacewicz**, AstraZeneca:
Leveraging R Programming for GxP System Development in Clinical Trials / Wykorzystanie programowania w języku R do rozwoju systemu GxP w badaniach klinicznych.

You are invited to an event where Anna Dacewicz from AstraZeneca Poland will discuss the development of a Centralized Monitoring system for clinical trials. The presentation will explore the challenges of creating systems that facilitate the analysis and reporting of clinical and operational data while considering user requirements. We will also delve into the use of R in building a comprehensive system. Furthermore, we will address the compliance requirements set by regulatory agencies overseeing clinical trials.

**Speech #2:**
**Łukasz Wałejko (TT Science)** will share his insights on building complex web applications using the Shiny framework, drawing from his remarkable experience across diverse programming languages like Python, TypeScript, and more (we counted 10!). While new to R with just six months of production use, Łukasz stands out as a rare example of a seasoned software engineer entering a space typically dominated by scientists transitioning into programming. His deep technical knowledge and versatility as both a backend and frontend developer make his perspective especially intriguing. Having worked on projects ranging from healthcare financial analysis to open-source tools for annotating wildlife footage, he will discuss not only the technical challenges and advantages of Shiny but also how his broader engineering mindset influences his approach to development in R.

AstraZeneca requires all meetup attendees to present identification upon entry. By registering for the event, I confirm that I have read and agree to comply with the Forum rules. The document can be found here:
