Question

我正在使用r-bloggers.com上的this食谱来绘制基本地图。

geocode（）为我要绘制的几个地址返回“NA”。返回“NA”的所有地址都有一个共同的属性，即它们包含丹麦字母“æ，Æ，ø，Ø，å，Å”，因此我强烈怀疑这是导致我出现问题的原因。

地址“Eskærvej50,5700Svendborg，denmark”返回错误消息

cannot open URL 'http://maps.googleapis.com/maps/api/geocode/json?
address=Esk%E6rvej%2050,%205700%20Svendborg,%20denmark&sensor=false': HTTP 
status was '400 Bad Request'
2: In FUN(X[[i]], ...) :
    geocoding failed for "Eskærvej 50, 5700 Svendborg, denmark".
  if accompanied by 500 Internal Server Error with using dsk, try google.

你知道有什么方法可以解决这个问题吗？

我的代码中的一个例子：

    # CREATE DATA FRAME
df.svendborg_locations <- tibble(location = c("Belvedere 60, 5700 Svendborg, denmark"
                                          ,"Fruerstuevej 17 B, 5700 Svendborg, denmark"

Answer 1

使用enc2utf8

geo.svendborg_locations <- geocode(enc2utf8(df.svendborg_locations$location))

这对我有用，虽然我在测试中受到限制...

使用OP的代码，我得到5行NA s，并附有500错误代码。

使用enc2utf8，我有两行NA s，两行都有错误geocode failed with status OVER_QUERY_LIMIT, location = "Lundbyvej 43, 5700 Svendborg, denmark"

非英语地址字母会导致geocode（）返回NA
