（更新：解决了 div 问题的高度/宽度；更改了问题）。我正在做：

output$mainplot <- renderGvis({gvisBubbleChart()}, chartid="foo")

结果：空白图。据我所知，我单独尝试了 gvisBubbleChart() 调用，它确实创建了 gvis 对象。

chartid="foo"需要进入这里gvisBubbleChart()给出的示例

rm(list = ls())
library(googleVis)
library(shiny)
times <- seq(c(ISOdate(2014,01,06)), by = "day", length.out = 100)
data1 <- round(runif(100, min = 100, max = 1000))
test <- round(runif(100, min = -10, max = 10))
my_data <- as.data.frame(cbind(as.character(times),data1,test))
colnames(my_data) <- c("time","data1","test")

ui =fluidPage(mainPanel(htmlOutput("view")))
server = function(input, output, session){
  datasetInput <- reactive({
    gvisBubbleChart(my_data,idvar="test", 
                    xvar="time", yvar="data1", chartid="foo")})
  output$view <- renderGvis({datasetInput()})
}
runApp(list(ui = ui, server = server))
