1 Answer1. The problem is that ggplots aes () takes first x and y arguments and then. The first problem is that when varSelectInput allows for multiple selections it will return a list of names which needs to be spliced into aes (). Splicing !!! however only works when using the dots ( see here ).

Shiny needs a bit more work with stylings than Dash, but that’s something you can quickly get used to. Still, the included styling with default Shiny apps means that there is a bit more work required to add custom styling to a Shiny app than a Dash app at a basic level. Winner: Dash.

This release features Plot Caching, an important new tool for improving performance and scalability in Shiny apps. If you’re not familiar with the term “caching”, it just means that when we perform a time-consuming operation, we save (cache) the results so that the next time that operation is requested, we can skip the actual Simple Shiny app, with and without plot caching. GitHub Gist: instantly share code, notes, and snippets. Shiny needs a bit more work with stylings than Dash, but that’s something you can quickly get used to.

By default, varSelectInput() and selectizeInput() use the JavaScript library selectize.js (https://github.com/selectize/selectize.js) to instead of the basic select input element.

By default, varSelectInput() and selectizeInput() use the JavaScript library selectize.js (https://github.com/selectize/selectize.js) to instead of the basic select input element. To use the standard HTML select input element, use selectInput() with selectize=FALSE. Note

For large numbers of choices, Shiny offers a "server-side selectize" option that massively improves performance and efficiency; see this selectize article on the Shiny Dev Center for details. Note The selectize input created from selectizeInput() allows deletion of the selected option even in a single select input, which will return an empty string as its value. shinyApp( ui = fluidPage( varSelectInput("variable_first", "Variable selected:", data = mtcars, multiple = TRUE), #varSelectInput("variable_remainder", "Variables selected:", data = mtcars, multiple = TRUE), verbatimTextOutput("text1"), verbatimTextOutput("text2") ), server = function(input, output) { output$text1 <- renderPrint({ input$variable_first }) #output$text2 <- renderPrint({ #input$variable_remainder #}) } ) By default, selectInput () and selectizeInput () use the JavaScript library selectize.js ( https://github.com/selectize/selectize.js) instead of the basic select input element.

2.1 Introduction. Now that you have a basic app under your belt, we can start to explore the details that make Shiny tick. As you saw in the previous chapter, Shiny encourages separation of the code that generates your user interface (the front end) from the code that drives your app’s behaviour (the back end).

Splicing !!! however only works when using the dots ( see here ). Shiny applications not supported in static R Markdown documents. Created on 2019-03-29 by the reprex package (v0.2.1) The above app basically doesn't work, since the varSelectInput allows all variables in the dataframe to be selected, including ones that really don't make any sense (non-factors, for the most part).

To use the standard HTML select input element, use selectInput() with selectize=FALSE. By default, varSelectInput() and selectizeInput() use the JavaScript library selectize.js (https://github.com/selectize/selectize.js) to instead of the basic select input element.
