addPolygons不会在闪亮的服务器上呈现形状数据

Question

我正在尝试使用巴西人状态创建一个地图，当我在UI文件中运行此代码时，它运行良好。但是我需要创建一个反应式地图，所以我在服务器文件上写了它。

地图很好但形状数据不...任何帮助？

 server <- shinyServer(function(session, input, output) {
    BrasilianStates <- readOGR("UFEBRASIL.shp",encoding = "UTF-8")
    output$map <- renderLeaflet

({                                                       #RENDERIZACAO DO MAPA


leaflet(data = BrasilianStates) %>% addTiles()%>%
addMarkers(data= CDDs,icon = iconeCDD, popup = nomes, clusterOptions = markerClusterOptions())%>%
addPolygons(data = BrasilianStates,weight = 2,
                        opacity = 1,
                        color = "#660000",
                        dashArray = "3",
                        fillOpacity = 0.7, highlight = highlightOptions(weight = 5, color = "#666",dashArray = "", fillOpacity = 0.7,
                                                                                                                bringToFront = TRUE)) })

当我只在控制台中运行时：

leaflet(data = BrasilianStates) %>% addTiles()%>%
addMarkers(data= CDDs,icon = iconeCDD, popup = nomes, clusterOptions = markerClusterOptions())%>%
addPolygons(data = BrasilianStates)

这些图在RStudio右侧的查看器选项卡中完美运行。

但是，当我在闪亮的应用程序中尝试服务器文件时，它不会呈现。

我想这可能是因为BrasilianStates是本地数据。看看这篇帖子给deploy shiny app that uses local data
