Question

我有一个动画情节，可以通过R（不是闪亮的应用程序）脚本正确显示：

load("HF.RData") # this contains the dataframe dt1.HF

p <- ggplot(dt1.HF, aes(x = tm, y = HF, colour = team)) +
  geom_point(aes(frame = sn, ids = tm), size = 5)

p <- ggplotly(p)

animation_opts(p, frame = 1000, transition = 500, easing = "linear",
           redraw = TRUE, mode = "immediate")

但是，我无法在具有相同数据帧的本地运行的闪亮应用程序（而不是闪亮的服务器）中显示此内容。目前，我的（简化的）闪亮应用是：

library(shiny)
library(ggplot2)
library(plotly)

shinyApp(
  shinyUI(
    fluidPage(
      plotOutput("HF.plot")
    )
  ),
  shinyServer(function(input, output, session) {

    load("HF.RData")

    output$HF.plot <- renderPlotly({
      p <- ggplot(dt1.HF, aes(x = tm, y = HF, colour = team)) +
        geom_point(aes(frame = sn, ids = tm), size = 5)
      p <- ggplotly(p)
      animation_opts(p, frame = 1000, transition = 500, easing = "linear",
                     redraw = TRUE, mode = "immediate")
    })
  })
)

我有什么想念的地方吗？

您需要使用renderPlotly和plotlyOutput。

library(shiny)
library(plotly)

ui <- fluidPage(
    plotlyOutput("plot")
)

server <- function(input, output, session) {
    output$plot <- renderPlotly({
        ggiris <- qplot(Petal.Width, Sepal.Length, data = iris, color = Species)
        ggplotly(ggiris)
    })
}

shinyApp(ui, server)

使用ggplot和plotly在R Shiny中渲染动画图
