Create an executable in R through the Shiny package

I wonder if it is possible to create an executable that goes directly to the panel generated by Shiny code without having to open the R and execute the codes 

library(shiny)

# Define UI for application that draws a histogram
ui <- fluidPage(

    # Application title
    titlePanel("Old Faithful Geyser Data"),

    # Sidebar with a slider input for number of bins 
    sidebarLayout(
        sidebarPanel(
            sliderInput("bins",
                        "Number of bins:",
                        min = 1,
                        max = 50,
                        value = 30)
        ),

        # Show a plot of the generated distribution
        mainPanel(
           plotOutput("distPlot")
        )
    )
)

# Define server logic required to draw a histogram
server <- function(input, output) {

    output$distPlot <- renderPlot({
        # generate bins based on input$bins from ui.R
        x    <- faithful[, 2]
        bins <- seq(min(x), max(x), length.out = input$bins + 1)

        # draw the histogram with the specified number of bins
        hist(x, breaks = bins, col = 'darkgray', border = 'white')
    })
}

# Run the application 
shinyApp(ui = ui, server = server)

My goal is that a user without R knowledge can use this panel, locally on your machine, without making it available on the web.

    Talk a little bit more about the environment you’ll be running in. Is it Windows? The other user has access to a shared server or folder in common with you?

  • The environment is Windows, as for the user, we have the option of compatible folder, I thank you

  • I recommend copying the R installation folder to the folder the user accesses. Then make the batch use the R executable in this folder to run Shiny.

Other Windows users can run R through the installation done on another machine if they have access to folder with R executables.

With this you just create an executable file (batch) with a content similar to this.

bat app.

caminho/do/R/na/pasta/compartilhada/Rscript.exe app.R

In this case your application would be the two files: app.R and app.bat. These two files should be in the same folder.

The good practice would be to install a Shiny server and users access the application the way you send the document. But the previous form breaks a branch.

Another alternative is to create a desktop application using Electron and Shiny as proposed in this talk.
