Using Spatial Data with R Shiny workshop

Join our workshop on Using Spatial Data with R Shiny, which is a part of our workshops for Ukraine series! 

Here’s some more info: 

Title: Using Spatial Data with R Shiny

Date: Thursday, November 23rd, 18:00 – 20:00 CET (Rome, Berlin, Paris timezone)

Speaker: Michael C. Rubin, is an Engineer, MIT Data Scientist and Co-Founder of Open Digital Agriculture (former ODAPES), a Start-up with the mission of democratizing Digital Agriculture. Open Digital Agriculture leverages R-Shiny, along with GIS technology and Artificial Intelligence to include the overlooked 540 Million smallholder farmers into the digital transformation. Michael was a 2 times speaker at the global R-Shiny conference.

Description: This workshop is about how to use R-Shiny in the context of geographic information systems (GIS). We will initially cover the R Leaflet package and learn how geographic information, from points to raster files, can be displayed in an R-Shiny app. During the work, we will develop a nice R-Shiny App, which allows us not only to display, but also to manipulate GIS related data. On the way there, we will touch some interesting Geostatistical concepts. Knowledge in R is required to follow the course and previous exposure to R-Shiny and some GIS techniques would be helpful, but you can follow the course even without it.

Minimal registration fee: 20 euro (or 20 USD or 800 UAH)

Visualising connection in R workshop

Join our workshop on Visualising connection in R, which is a part of our workshops for Ukraine series! 

Here’s some more info: 

Title: Visualising connection in R
Date: Thursday, November 9th, 19:00 – 21:00 CEST (Rome, Berlin, Paris timezone)
Speaker: Rita Giordano is a freelance data visualisation consultant and scientific illustrator based in the UK. By training, she is a physicist who holds a PhD in statistics applied to structural biology. She has extensive experience in research and data science.

Network Analysis with R workshop

Join our workshop on Network Analysis with R, which is a part of our workshops for Ukraine series! 

Here’s some more info: 

Title: Network Analysis with R

Date: Thursday, October 26th, 18:00 – 20:00 CEST (Rome, Berlin, Paris timezone)

Speaker: David Schoch is the team lead for “Transparent Social Analytics” in the Department Computational Social Science at GESIS in Cologne. Before joining GESIS, David was a Presidential Fellow in the Department of Sociology at the University of Manchester, affiliated with the “Mitchell Centre for Social Network Analysis”. He has a PhD in Computer Science from the University of Konstanz and is the creator and maintainer of several network analysis R packages.

Description: Network analysis is a multidisciplinary field that delves into the intricate web of connections and interactions among entities, whether they are individuals, organizations, or nodes in a complex system. By employing graph theory, statistical methods, and computational tools, network analysis unveils the hidden patterns, structures, and dynamics that underlie these relationships.

In this workshop, I will introduce the package ecosystem for network analysis in R. I provide an overview of the key packages to conduct network studies and discuss some practical aspects. No network theory will be introduced, but I provide pointers for those who are interested to learn more beyond practical skills.

Introduction to Topic Modelling in R and Python workshop

Join our workshop on Introduction to Topic Modelling in R and Python, which is a part of our workshops for Ukraine series! 


Here’s some more info: 

Title: Introduction to Topic Modelling in R and Python

Date: Thursday, October 19th, 18:00 – 20:00 CEST (Rome, Berlin, Paris timezone)

Speaker: Christian Czymara is a postdoc fellow at Tel Aviv University. His research focuses on attitudes, immigration, and political communication using quantitative and computational methods as well as natural language processing.

Description: This workshop offers an in-depth exploration of topic models, which allow extracting meaningful insights from extensive text corpora while minimizing the reliance on prior assumptions or annotated data. The workshop will start with the basics of text data preprocessing and progress to a general understanding of the underlying principles of topic modeling. It will cover a range of topic modeling techniques, such as Structural Topic Models, BiTerm, and Keyword Assisted Topic Models in R, and BERTopic in Python. We will explore the cases where each model is particularly promising. Participants will learn about the practical considerations when choosing a topic modeling algorithm, and how to apply these techniques to their own data. The lecture will be of interest to researchers and practitioners who are interested in extracting insights from large volumes of textual data, such as social media, news articles, or scientific publications.

Here’s some more info: 

Title: Introduction to Qualitative Comparative Analysis (QCA) using R

Date: Thursday, October 5th, 18:00 – 20:00 CEST (Rome, Berlin, Paris timezone)

Speaker: Ingo Rohlfing, Ingo Rohlfing is Professor of Methods of Empirical Social Research at the University of Passau. He is doing research on social science methods with a focus on qualitative methods (case studies and process tracing), Qualitative Comparative Analysis, multimethod research and research integrity.

Description: What are the conditions that produce stable coalition governments? What conditions are necessary for married couples not getting divorced? If you are interested in research questions like these or similar ones, QCA should be one of the first methods to consider for answering them. QCA is the go-to method for analyzing set relationships using any number of cases (small, medium, large) and with any kind of data (micro, meso, macro).

The participants of this course are introduced to the fundamentals of set relations and QCA, and the workflow of a QCA study using R. You are be introduced to the basic principles and requirements of coherent QCA designs and learn how to implement them using R. We cover all fundamental steps of a QCA study, including calibration; a necessity analysis (potentially); truth table formation; truth table minimization and interpretation of results.

Build serverless shiny application via Github page

Simple guide for simple shiny application 

TL;DR

I made shiny application in github page with quarto.

You can check code in my github repository and result, result2

How we use shiny

Shiny is R package to make user utilize R with web browser without install it.

So my company utilizes shiny to provide statistical analysis for doctors (who don’t know R but need statistics).

Behind shiny

As you know, shiny is consisted with 2 part. UI and Server

You may think just UI is channel to both get input (data) from user and return calculated output (result) to user.
and server is just calculator

It means, server requires dynamic calculation that may change, not fixed contents (it called as static web page)

To achieve dynamic calculation, there are several options.

We can use shinyapps.io, posit connect, or deploy own shiny server in other cloud like AWS / azure / GCP …

These options can be categorized into two main categories: free but with limited features, or feature-rich but paid.

There is no single right answer, but I use shinyapps.io in see toy level project or deploy using shiny server in company’s cloud server which is not just toy level.
