我正在尝试在Shiny中创建一个Leaflet，它根据许多参数过滤数据集，并仅绘制用户选择的那些点。一切都有效，除了一个关键部分：当我运行应用程序时，我得到＆＃34;错误：未找到点数据;请为addMarkers提供数据和/或lng / lat参数＆＃34;信息。 编辑：即使input$question1 == FALSE我也收到此错误。这对我来说很有意义，因为我没有为绘图定义else或初始数据集，但它可能是相关的。
以下是dput的{{1}}部分：
dataset以下是我用来生成过滤值和renderLeaflet代码的反应函数：
dput(dataset[1:10,14:24])
structure(list(target.pops = structure(c(6L,
6L, 18L, 31L, 21L, 27L, 27L, 18L, 6L, 27L), .Label = c("DD Adult",
"DD Adult, DD Child", "DD Adult, DD Child, MH Adult", "DD Adult, DD Child,
MH Adult, MH Child",

任何想法出了什么问题？提前感谢任何见解！
答案 0 :(得分：0)
我能解决这个问题。卡住一周后，我将addMarkers语法更改为
addMarkers(data = points())
它按预期工作。
