Shiny apps often need to save data, either to load it back into a different session or to simply log some information.
However, common methods of storing data from R may not work well with Shiny. Functions like write.csv() and saveRDS() save data locally, but consider how shinyapps.io works. Shinyapps.io is a popular server for hosting Shiny apps. It is designed to distribute your Shiny app across different servers, which means that if a file is saved during one session on some server, then loading the app again later will probably direct you to a different server where the previously saved file doesn’t exist.

I was mainly focused on recreating functionality found in other “dashboarding” applications. When looking for options, I found that htmlwidgets were the closest to what companies usually expect. However, while they are great for client-side interactivity, I often hit walls with them when I try to add click-through interactivity because the functionality is either not there, is very limited, or is bloated. With r2d3 there is more work, but the gains in customization and interactivity make it by far the best choice, in my opinion. Watch if R is running from Shiny. 4 tips for creating interactive visualisations with Shiny. Shinymeta: Record and Expose Shiny App Logic using Metaprogramming. Sortable: drag-and-drop for shiny. By Andrie de Vries Andrie de Vries is the author of “R for Dummies” and a Solutions Engineer at RStudio Earlier this year I was a student on the RStudio Instructor Training, taught by the inspiratational Greg Wilson.
I remember several tips from this course, for example that you should always try to draw a concept map of the material you are teaching. And, secondly, that you should make liberal use of formative assessment during your teaching. A formative question helps the student grow their understanding of a topic, in contrast to a normative question that attempts to assess the skills of the student. This made me wonder what it would take to create ranking type questions in learnr tutorials. How to select all the Input at once from selectInput function in R. Informal intro to async Shiny – Joe Cheng. Hello, R and/or Shiny user!

One of the most common web development term you should know : rendering. How to Use CSS to Style Your R Shiny Projects. I hope you will give me 7 minutes to convince you why CSS is a good thing, and why you should be using it in your projects. In this post I’ll give you a little overview of CSS and I’ll discuss adding CSS to R Shiny. And in another article I’ll describe a time-saving way to produce CSS — the wonderful SASS, which is like a CSS factory. So, R Shiny provides scalability, fast prototyping, and power, but without CSS, it looks like this: With CSS, it can look like this:

Secure your Shiny apps (against SQL injection) Shiny takes inputs from UI elements and sends them to the server, where the application can access them as R variables. While Shiny has security measures in place, as in any typical web application, it remains the developer’s responsibility to sanitize the inputs before using them.
