【问题描述】:
当我想在 shinyApp 中使用 labels 和 colors 参数和 addLegend() 函数时,图例显示在楼梯中,如下所示。
但是,如果我仅在 shinyApp 之外使用 leaflet 渲染地图,则标签将正确内联显示。
我见过this post 有同样的问题,但他们不是可复制的例子,所以我决定发布我自己的问题。
- 显示错误(闪亮的仪表板)
- 正确显示(单张独立)
我做了一个可复制的例子:
# ----- Load and install missing packages
packages<-c("shiny","shinydashboard","leaflet")
new.packages <- packages[!(packages %in% installed.packages()[,"Package"])]
if(length(new.packages)) install.packages(new.packages)
lapply(packages, require, character.only = TRUE)
rm(list = c("new.packages","packages"))
# ----- Reproductible Example
# ----- UI
header <- dashboardHeader(title = "Repoductible Example")
sidebar <- dashboardSidebar(
sidebarMenu(
menuItem("map", tabName = "map", icon = icon("globe",lib="font-awesome"))
)
)
body <- dashboardBody(
tabItems(
tabItem(tabName= "map",
column(width=12,
leafletOutput("mapExmpl", width="100%",height=600)))
)
)
ui <- dashboardPage(header, sidebar, body,skin="blue")
# ----- Server
server <- function(input, output) {
labels=c("Label1","Label2","Label3","Label4","Label5")
colors<-c(rgb(243,87,26,maxColorValue=256)
,rgb(225,205,19,maxColorValue=256)
,rgb(62,3,79,maxColorValue=256)
,rgb(17,126,147,maxColorValue = 256)
,rgb(61,255,80,maxColorValue=256))
output$mapExmpl<-renderLeaflet({
leaflet()%>%addTiles(
)%>%
addLegend("bottomright", colors = colors, labels =labels ,
title = "Typo",
opacity = 1
)
})
}
shinyApp(ui,server)
