shiny-markdown 和 ggvis 的问题

Question

我遇到了一些问题，包括将 ggvis 绘制到闪亮降价中。例如，代码

---
title: "testShiny"
runtime: shiny
output: html_document
---

```{r, fig.height=3}

require(ggvis)
require(knitr)
require(shiny)

women %>%
  ggvis(x= ~height, y = ~weight) %>%
  layer_points()%>%
  bind_shiny("p")

ggvisOutput("p")


```

导致ggvisOutput 在线条中无所事事

women %>%
  ggvis(x= ~height, y = ~weight) %>%
  layer_points()%>%
  bind_shiny("p")    

产生一个情节而不是清除output$p。我认为bind_shiny(vis, id) 是这里的问题。

任何想法如何解决这个问题？

PS：我的 sessionInfo()

Answer 1

我对上面的代码没有任何问题——我认为你不需要ggvisOutput("p") 或bind_shiny("p")。在我删除它之后，它编译成一个闪亮的降价文档，ggvis 显示得很好。这是我的会话信息：

编辑：我通过 r-studio 编译：版本 0.98.977

你可能有一个旧版本的 shiny/knitr/ggvis/rstudio 。

EDIT2：我在闪亮的降价文档中包含了一个可以正确编译的可重现示例：

---
title: "testShiny"
runtime: shiny
output: html_document
---

```{r defineWidget, fig.height=3}
require(ggvis)
require(knitr)
require(shiny)

widget = function(dataset) {
  shinyApp(
    ui = navbarPage("test widget",
      tabPanel("Dataset",
        fluidPage(
          ggvisOutput("gg_plot")
        ) #fluid page
      ),  #tab panel

      #END TABS
      responsive = FALSE
    ), #ui  

    #SERVER
    server = function(input, output, session) {
      dataset %>% ggvis(x = ~mpg, y = ~hp) %>% layer_points() %>%
        bind_shiny("gg_plot")
    } #server

  ) #shinyAPP

}
```

```{r callWidget}
widget(mtcars)
```
