r - 在 Shiny 应用程序启动时更改 RStudio 窗口的大小

Question

我正在使用 RStudio IDE 开发 Shiny 的应用程序。启动应用程序时，我通常使用 RunApp 按钮:在窗口中运行。这将在具有特定宽度和高度的窗口中打开应用程序。

有没有办法改变这个窗口的宽度，所以每次我启动应用程序时都会在更宽的窗口中显示？

您可以尝试 runGadget 选项:

library(shiny)

ui <- fluidPage(
  titlePanel("Hello Shiny!"),
  sidebarLayout(
    sidebarPanel(sliderInput(inputId = "bins", label = "Number of bins:", min = 1, max = 50, value = 30)),
    mainPanel(plotOutput(outputId = "distPlot"))
  )
)

server <- function(input, output) {
  output$distPlot <- renderPlot({
    x    <- faithful$waiting
    bins <- seq(min(x), max(x), length.out = input$bins + 1)
    hist(x, breaks = bins, col = "#75AADB", border = "white",
         xlab = "Waiting time to next eruption (in mins)",
         main = "Histogram of waiting times")
    })
}

# Run in a dialog within R Studio
runGadget(ui, server, viewer = dialogViewer("Dialog Title", width = 1200, height = 600))

# Run in Viewer pane
runGadget(ui, server, viewer = paneViewer(minHeight = 500))

# Run in browser
runGadget(ui, server, viewer = browserViewer(browser = getOption("browser")))
