为什么当我将这两个地理数据集连接在一起时，某些值会被 NA 填充？
Why when I join these two geographic datasets together do some values get filled with NAs?
我正在尝试将两个数据集连接在一起——来自 Natural Earth 子集的数据集仅包含欧洲国家 (europe_map) 和欧洲位置列表 (europe_places)。
这是数据集的 headers：

我使用以下代码将数据集连接在一起：
europe.map1<-st_join(europe_places, europe_map, by="Country")
但是当我输入威尼斯、里斯本和哥本哈根的条目时，尽管 Country 的条目包含与 europe_map 数据集中的值相匹配的值，但它们的值是 NA。
根据上面的评论，您没有正确指定空间连接。我想这就是您要找的：
europe.map1<- st_join(europe_places, europe_map,
join=st_within, # always best to specify the method
left=TRUE)
这应该适合你。也就是说，您可能想要调换 europe_places 和 europe_map 的顺序。我不确定你的目标。您可以在 sf 包 here.
