非英文地址字母导致 geocode() 到 return NA

Question

我正在使用来自 r-bloggers.com 的 this 配方来绘制基本地图。

geocode() returns "NA" 我试图绘制的几个地址。所有返回 "NA" 的地址都有一个共同属性，即它们包含丹麦语字母“æ、Æ、ø、Ø、å、Å”，所以我强烈怀疑这就是导致我出现问题的原因。

返回地址 "Eskærvej 50, 5700 Svendborg, denmark"

的错误消息

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.

你知道解决这个问题的方法吗？

我的代码中的示例：

    # 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，尽管我在测试中遇到了速率限制...

使用 OP 的代码，我得到了 5 行 NAs，伴随着 500 错误代码。

使用 enc2utf8，我得到 2 行 NAs，均有错误 geocode failed with status OVER_QUERY_LIMIT, location = "Lundbyvej 43, 5700 Svendborg, denmark"
