非常棒的工作!我最近在使用baidumap的时候遇到一个问题:分别用ggmap和baidumap获取同一位置(如中国矿业大学北京),然后将他们获取的位置标在leaflet地图上,发现差别好大呀!Why?是baidumap不准确吗?
下面是我的代码

library(leaflet)
library(baidumap)
## getcoordinate return vector
loc<-getCoordinate('中国矿业大学(北京)', formatted = T) # character
library(ggmap)
## geocode return dataframe
ggloc<-geocode("China University of Mining and Technology,Beijing")
## plot
CUMTB %
addTiles() %>% # Add default OpenStreetMap map tiles
addMarkers(lng=loc[1], lat=loc[2],
popup="China University of Mining and Technology,Beijing")
CUMTB # Print
ggCUMTB %
addTiles() %>% # Add default OpenStreetMap map tiles
addMarkers(lng=ggloc$lon, lat=ggloc$lat,
popup="China University of Mining and Technology,Beijing")
ggCUMTB # Print
[未知用户] 这个是devtools的问题,试试httr::set_config( httr::config( ssl_verifypeer = 0L ) )能处理不..
[未知用户] 这个是因为不同源的经纬度需要相互转化,比如百度和谷歌的经纬度,相互会有几百米的偏移..
百度有提供一些转化的API接口..

[未知用户] 谢谢,明白了!逛了一圈,百度不够open啊!需要ak,就得“卖身”!!

安装不了啊急
[未知用户] 里面提到: there is no package called 'Rcpp'
所以你需要
install.packages("Rcpp")

老师,这段代码直接运行可以做出图,但是再rmarkdown文档里knit HTML时却会出现

[未知用户] 我也出现这种情况了,估计是编码问题,我试着把中文转成拼音就可以了,有3个无法识别改为 nanning --> nanzningz;nanchang --> nachang 常州是怎么也识别不了,看你有什么别的方法,我试过UTF-8,GBk等格式都不行
