我有一个仪表板，其中1个选项卡使用由rchart库创建的绘图，其他选项卡使用d3 js创建文字云。 不幸的是，我的rChart没有显示并且正在生成此错误：
TypeError: d3.select(...).append(...).datum is not a function
.datum(data)
但如果我删除了ui.R中的单词云标签，那么我的rChart情节就会开始显示。 当我尝试在我的ui.r文件中显示两个选项卡时，存在一些冲突。 我正在闪亮的服务器上运行我的闪亮应用程序。所以，目录结构是
/myapp
ui.r
server.r
cloud.js
/assets
/www
/js
d3.js
d3.layout.cloud.js
这是我的ui.r：
require(rCharts) reactiveNetwork <- function (outputId) { HTML(paste("<div id=\"", outputId, "\" class=\"shiny-network-output\"></svg></div>", sep="")) } shinyUI(pageWithSidebar( headerPanel("rCharts: Interactive Charts from R | NVD3"), sidebarPanel( selectInput(inputId = "gender", label = "Choose Gender", choices = c("Male", "Female"), selected = "Male"), selectInput(inputId = "type", label = "Choose Chart Type", choices = c("multiBarChart", "multiBarHorizontalChart"), selected = "multiBarChart"), checkboxInput(inputId = "stack", label = strong("Stack Bars?"), value = FALSE) ), mainPanel( tabsetPanel( tabPanel("rchart", showOutput("myChart", "nvd3")), tabPanel("d3", h6("click on the word to see chat sessions related to it"), includeHTML("cloud.js"), reactiveNetwork(outputId = "cloud") ) ) #tabPanel )#mainPanel ))
server.r
require(rCharts) shinyServer(function(input, output) { output$myChart <- renderChart({ hair_eye = as.data.frame(HairEyeColor) p6 <- nPlot(Freq ~ Hair, group = 'Eye', data = subset(hair_eye, Sex == "Male"), type = "multiBarChart", dom = 'myChart', width = 800) # p6$chart(color = c('brown', 'blue', '#594c26', 'green'), stacked = input$stack) return(p6) }) output$cloud <- reactivePlot(function(){ }) })

d3.js可以从github获得，如果你没有。
答案 0 :(得分：0)
解决。 共有2个不同版本的d3.js.我不得不删除另一个。
