闪亮的带有Shiny工具的有向列表

Question

从this的问题中，我想知道如何以闪亮的方式显示dy_graph list对象。下面的代码创建了它，但我不是html方面的专家，阅读htmltools手册也没有帮助。本质上，我需要这个部分的htmltools::browsable(htmltools::tagList(dy_graph))修改，以渲染在光泽。

# create the time series
temperature <- ts(frequency = 12, start = c(1980, 1),
              data = c(7.0, 6.9, 9.5, 14.5, 18.2, 21.5, 
                       25.2, 26.5, 23.3, 18.3, 13.9, 9.6))
rainfall <- ts(frequency = 12, start = c(1980, 1),
           data = c(49.9, 71.5, 106.4, 129.2, 144.0, 176.0, 
                    135.6, 148.5, 216.4, 194.1, 95.6, 54.4))

# create a list of dygraphs objects
library(dygraphs)
library(htmltools)
dy_graph <- list(
  dygraphs::dygraph(temperature, group="temp_rain", main="temperature"),
  dygraphs::dygraph(rainfall, group="temp_rain", main="rainfall")
)  # end list

# render the dygraphs objects using htmltools
htmltools::browsable(htmltools::tagList(dy_graph))

Answer 1

您可以使用uiOutput和renderUI来实现这一点。你可以这样做：

library(shiny)
library(dygraphs)

ui <- fluidPage(

  uiOutput("dygraph")
)


server <- function(input, output)
{

  output$dygraph <- renderUI({
    # create the time series
    temperature <- ts(frequency = 12, start = c(1980, 1),
                      data = c(7.0, 6.9, 9.5, 14.5, 18.2, 21.5, 
                               25.2, 26.5, 23.3, 18.3, 13.9, 9.6))
    rainfall <- ts(frequency = 12, start = c(1980, 1),
                   data = c(49.9, 71.5, 106.4, 129.2, 144.0, 176.0, 
                            135.6, 148.5, 216.4, 194.1, 95.6, 54.4))

    dy_graph <- list(
      dygraphs::dygraph(temperature, group="temp_rain", main="temperature"),
      dygraphs::dygraph(rainfall, group="temp_rain", main="rainfall")
    )  

    tagList(dy_graph)
  })

}

shinyApp(ui = ui, server = server)
