一、简介最受欢迎的JS的开源交互式地图包（ most popular open-source JavaScript libraries for interactive maps），可以直接加载 OpenStreetMap, Mapbox, and CartoDB的底图数据（谢天谢地，这些底图都没有被墙，热泪盈眶啊有木有）。下面就是用Leaflet做的一个地图：   > 交互地图浏览（缩放、平移）install.packages("leaflet")m <- leaflet()管道操作符“%>%”来实现，它的主要作用就是把前面的语句（变量）传递给下一个语句，并且作为第一个参数使用，上面那三个语句，利用管道操作符来写，如下,输出结果是完全一样的，但是语句变得简单了。leaflet()%>%addTiles()%>%addMarkers(lng=116.391, lat=39.912, popup="这里是北京")leaflet() %>% addTiles() addTiles(leaflet())m<- leaflet()leaflet()%>%setView(lng=116.38,lat=39.9,zoom=3)%>%addTiles()df = data.frame(Lat = rnorm(100), Lon = rnorm(100))m <-leaflet(df)df %>%leaflet()%>%addCircles()library(sp)
