Shiny 0.10.2
Shiny v0.10.2 has been released to CRAN. To install it:
install.packages('shiny')
This version of Shiny requires R 3.0.0 or higher (note the current version of R is 3.1.1). R 2.15.x is no longer supported.
Here are the most prominent changes:
-
File uploading via
fileInput()now works for Internet Explorer 8 and 9. Note, however, that IE 8/9 do not support multiple files from a single file input. If you need to upload multiple files, you must use one file input for each file. Unlike in modern web browsers, no progress bar will display when uploading files in IE 8/9. -
Shiny now supports single-file applications: instead of needing two separate files,
server.Randui.R, you can now create an application with single file namedapp.R. This also makes it easier to distribute example Shiny code, because you can run an entire app by simply copying and pasting the code for a single-file app into the R console. Here’s a simple example of a single-file app:
## app.R
server <- function(input, output) {
output$distPlot <- renderPlot({
hist(rnorm(input$obs), col = 'darkgray', border = 'white')
})
}
ui <- shinyUI(fluidPage(
sidebarLayout(
sidebarPanel(
sliderInput("obs", "Number of observations:",
min = 10, max = 500, value = 100)
),
mainPanel(plotOutput("distPlot"))
)
))
shinyApp(ui = ui, server = server)
See the single-file app article for more.
- We’ve added progress bars, which allow you to indicate to users that something is happening when there’s a long-running computation. The progress bar will show at the top of the browser window, as shown here:

- We’ve upgraded the DataTables Javascript library from 1.9.4 to 1.10.2. We’ve tried to support backward compatibility as much as possible, but this might be a breaking change if you’ve customized the DataTables options in your apps. This is because some option names have changed; for example,
aLengthMenuhas been renamed tolengthMenu. Please read the article on DataTables on the Shiny website for more information about updating Shiny apps that use DataTables 1.9.4.
In addition to the changes listed above, there are some smaller updates:
-
Searching in DataTables is case-insensitive and the search strings are not treated as regular expressions by default now. If you want case-sensitive searching or regular expressions, you can use the configuration options
search$caseInsensitiveandsearch$regex, e.g.renderDataTable(..., options = list(search = list(caseInsensitve = FALSE, regex = TRUE))). -
Shiny has switched from reference classes to R6.
-
Reactive log performance has been greatly improved.
-
Exported
createWebDependency. It takes anhtmltools::htmlDependencyobject and makes it available over Shiny’s built-in web server. -
Custom output bindings can now render
htmltools::htmlDependencyobjects at runtime usingShiny.renderDependencies().
