带有tmap的交互式地图不会显示在Shiny app中,但会显示在Rstudio viewer中
我用tmap创建的交互式地图确实会显示在RStudio查看器中,但是,如果我尝试将其包含在我闪亮的应用程序中,它不会出现。我使用了tmap_传单函数、RenderLablet和传单输出。有人知道如何解决这个问题吗 下面是我在Shining应用程序中使用的示例代码:带有tmap的交互式地图不会显示在Shiny app中,但会显示在Rstudio viewer中,r,shiny,leaflet,maps,tmap,R,Shiny,Leaflet,Maps,Tmap,我用tmap创建的交互式地图确实会显示在RStudio查看器中,但是,如果我尝试将其包含在我闪亮的应用程序中,它不会出现。我使用了tmap_传单函数、RenderLablet和传单输出。有人知道如何解决这个问题吗 下面是我在Shining应用程序中使用的示例代码: library(shiny) library(c(tmap,tmaptools,leaflet)) ui <- fluidPage( leafletOutput("test")) server

ui通过一些虚拟数据,我可以看到地图
我不确定您是否可以这样加载包:library(c(tmap、tmaptools、传单))
它给了我这个错误:
库(c(tmap、tmaptools、传单)中出错:'package'muss

我不认为有一个参数叫做view.legend.position
。尝试使用图例。仅定位
我认为问题来自方面。(下面的示例不使用它们)

你能提供一些数据吗?非常感谢你的回复!如果没有面,它也可以很好地处理原始数据:)。仍然想知道为什么在刻面上是不可能的?至于图书馆,那是一个打字错误。我确实在我的文件中分别加载了它们。请注意,view.legend.position最近已替换了tm_view函数()中的legend.position。正确,我仍在使用tmap 1.11。我不知道它将如何在地图上放置不同的面。你知道在tmap上使用刻面的例子吗?
