It is highly recommended that this be used for testing and debugging only, and not included in production apps! </p> <h3>Usage</h3> <pre> profvis_ui(id) profvis_server(input, output, session, dir = ".") </pre> <h3>Arguments</h3> <table summary="R argblock"> <tr valign="top"><td><code>id</code></td> <td> <p>Output id from <code>profvis_server</code>.</p> </td></tr> <tr valign="top"><td><code>input, output, session</code></td> <td> <p>Arguments provided by <code><a href="../../shiny/html/callModule.html">callModule</a></code>.</p> </td></tr> <tr valign="top"><td><code>dir</code></td> <td> <p>Output directory to save Rprof files.</p> </td></tr> </table> <h3>Details</h3> <p>The usual way to use Profvis with Shiny is to simply call 'profvis(shiny::runApp())', but this may not always be possible or desirable: first, if you only want to profile a particular interaction in the Shiny app and not capture all the calculations involved in starting up the app and getting it into the correct state; and second, if you're trying to profile an application that's been deployed to a server. </p> <p>For more details on how to invoke Shiny modules, see [this article](https://shiny.rstudio.com/articles/modules.html). </p> <h3>Examples</h3> <pre> # In order to avoid "Hit <Return> to see next plot" prompts, # run this example with `example(profvis_ui, ask=FALSE)` if(interactive()) { library(shiny) library(ggplot2) shinyApp( fluidPage( plotOutput("plot"), actionButton("new", "New plot"), profvis_ui("profiler") ), function(input, output, session) { callModule(profvis_server, "profiler") output$plot <- renderPlot({ input$new ggplot(diamonds, aes(carat, price)) + geom_point() }) } ) } </pre> <hr /><div style="text-align: center;">[Package <em>profvis</em> version 0.3.7 <a href="00Index.html">Index</a>]</div> </body></html>
