# shinyscroll

Programatically scroll in Shiny.

## Installation

Install it with `remotes` from Github:

``` r

# install.packages("remotes")

remotes::install_github("JohnCoene/shinyscroll")

```

## Example

{shinyscroll} was created to solve the use case below, where I want the window to scroll to a plot dynamically created by a click in a DT table.

``` r

library(DT)

library(shiny)

library(shinyscroll)

ui <- fluidPage(

  use_shinyscroll(),

  h1("shinyscroll"),

  p("Select a row"),

  DTOutput("table"),

  plotOutput("plot")

)

server <- function(input, output, session){

  output$table <- renderDT({

    datatable(cars, selection = "single", options = list(pageLength = 20L))

  })

  dataset <- eventReactive(input$table_rows_selected, {

    scroll("plot") # scroll to plot

    runif(100)

  })

  output$plot <- renderPlot(plot(dataset()))

}

shinyApp(ui, server)

```
