以下学习的三个例子均copy自网络，调试运行后的代码和运行结果复制如下，以备后用。
一、地图块
library(ggplot2)
library(baidumap)
library(ggmap)
options(baidumap.key = 'XXX')
q <- getBaiduMap('广州白云山', width=600, height=600, zoom=18, scale = 2, messaging=FALSE)
ggmap(q)
二、热力图
library(REmap)
options(remap.js.web=T)
data<- read.csv(file="/home/linbin/文档/R/cityvaluetop10.csv",header=T)
theme1 <- get_theme(theme = "none",
lineColor = "white",
backgroundColor = "white",
titleColor = "#fff",
borderColor = "blue",
regionColor = "grey",
labelShow = T,
pointShow = F,
pointColor = "gold")
remapH(data,
maptype = 'china',
theme = theme1,
blurSize = 70,
color = "red",
minAlpha = 10,
opacity = 1,)
cityvaluetop10.csv 文件数据格式
lon,lat,prob
114.394818,23.408004,0.85
110.50664,28.695864,0.8
112.920664,26.695864,0.8
112.720664,26.695864,0.8
113.487804,34.157184,0.75
...
三、迁移图
library(ggplot2)
library(baidumap)
library(REmap)
library(ggmap)
options(baidumap.key = 'XXX')
options(remap.ak = "XXX")
#get_city_coord("天津")
#city_list <- c("beijing","tianjin","hefei","suzhou","chongqing")
#get_geo_position(city_list)
destination<- c("beijing","tianjin","nanjing","hefei","chengdu") #终点
origin<- rep("guangzhou",length(destination))
map_data<- data.frame(origin,destination)
head(map_data)
map_out<-remap(mapdata=map_data, #流向地图的数据源（依次为起点、终点两列）
title="我是标题", #设置主标题
subtitle="我是副标题", #设置副标题
theme =get_theme(theme="Sky")) #设置主题（默认主题一共有三套：“Dark”,“Bright,”Sky“）
plot(map_out)
