With ggplot2 graphics, the code in renderPlot should return a ggplot object; if instead the code prints the ggplot2 object with something like print(p), then the coordinates for interactive graphics will not be properly scaled to the data space. To run the example, type: > library (shiny) > runExample ("01_hello") Shiny applications have two components: a user-interface definition and a server script.

Fortunately I discovered that there are many examples of R Shiny code out there which I could use, so I started immediately. Shiny is a web framework for R.

The Hello Shiny example is a simple application that generates a random distribution with a configurable number of observations and then plots it. ui: definition of the interface layout (where are the buttons, text input, plot output, etc.) Here is a reproducible example: I initially had a problem when using ggplotly so checked if it was plotly more broardly. I was really surprised how easy it is to start writing code in R. The opportunity to apply this knowledge and develop my skills in R Shiny presented itself quickly. I know that there are similar questions already answered on stackoverflow. To learn more about what {bslib} and {thematic} are able to do, see … timosch29 / Example Flexdashboard with Shiny and Plotly.Rmd.

The corresponding HTML output tag should be div or img and have the CSS class name shiny-plot-output.. Interactive plots. A shiny application is an app.R file (it must be named like that) containing 3 elements:. ... For an extensive example of Shiny and Leaflet working together, take a look at the SuperZip Explorer example app (note the “Get Code” button at the top of the page). This ‘auto theming’ behavior that {thematic} provides works great in Shiny with any CSS framework (not just {bslib}).Also, more generally, {thematic} can help simplify plot theming inside any R environment, using any graphics device, and also makes it super easy to use Google Fonts inside your R plots. I am using plotlyOutput() instead of plotOutput(), and following is how I have tried to change the height of a fluidRow():. Star 0 Fork 0; Star Code Revisions 3. This makes it easy to add features like selecting points and regions, as well as zooming in and out of images. Details. fluidRow( plotlyOutput("plot", height = 200) ) If you run the chunks in Rstudio rather than Running the document the plot renders in the viewer so I'm thinking it might be related to issues #2748 and #2774 (see also ropensci/plotly#717) 15.1 Stand-alone shiny application. But, unfortunately, they do not work for me. I want to check a condition on a reactive input value. Contribute to rstudio/shiny-examples development by creating an account on GitHub. As of version 0.12.0, Shiny has built-in support for interacting with static plots generated by R’s base graphics functions, and those generated by ggplot2.
