与ggplot2干扰？无法访问map_data [英] tidyverse interfering with ggplot2? cannot access map_data

错误：ggplot2不知道如何处理class列表中的数据
  

我可以调用 map_data（county），直到加载 tidyverse 那么它就会失败。如何通过 tidyverse 加载加载县地图数据？

解决方案

在测试之后从上面传递了评论：

我猜测虚线以下的项目来自控制台消息，但你真的应该澄清。似乎'purrr'中的地图功能掩盖了'maps'包中的地图功能。如果您需要映射（的地理概念）比您需要（映射）的（功能 - 计算机语言概念）更多的原因，则可以颠倒加载tidyverse和映射的顺序。您可能需要开始新的会话才能成功。库函数检查一个包是否已经被加载，如果是这样的话，什么也不做。

对术语的评论。我的猜测是，映射的计算机操作实际上是从多种应用程序（一种功能到临时结果）的收缩。如果有机会返回并将其重命名为与地理概念类似的内容，则可以将其命名为 route（） -ing。地理上的地图似乎是一个静态的二维或三维对象或贴图，以便在这样的对象上放置位置。

似乎成功了：

 ＃在新鲜的会话中（默认情况下，我的个人资料会附加ggplot2）

 summary（）：dplyr，Hmisc 
> cty0 = ggplot2 :: map_data（county）
 
附加包：'maps'
 
下面的对象被'package：purrr'掩盖：
 
 map 
  

Running these commands in the console, the output is:

> cty0 = ggplot2::map_data("county")
> library(tidyverse)

> cty0 = ggplot2::map_data("county")
Error: ggplot2 doesn't know how to deal with data of class list

I can call map_data("county") fine until tidyverseis loaded, then it fails. How do I load a county map data with tidyverse loaded?

解决方案

Transferred the comment from above after testing:

I'm guessing that the items below the dashed line are from the console messages , but you really should clarify that . Seems likely that the map function in 'purrr' is masking the map function in the 'maps' package. You could reverse the order of loading tidyverse and maps if there were a reason that you needed the (geographic notion of) "mapping" more than you needed the (functional-computer language notion of) "mapping". You probably need to start a new session for that to succeed. The library function checks to see of a package is already loaded and if so does nothing.

A comment on terminology. My guess is that the computer operation of "mapping" is actually a contraction from "multiple application" (of a function to interim results). If there were a chance to go back and rename it to something that would be similar to a geographic concept, it might be named route()-ing. A geographic "map" would seem to be a static two or three-dimensional object or "mapping" to be placement of positions on such an object.

Seems to succeed:

# In a fresh session (and my profile attaches ggplot2 by default)
> library(tidyverse)
Loading tidyverse: tibble
Loading tidyverse: tidyr
Loading tidyverse: readr
Loading tidyverse: purrr
Loading tidyverse: dplyr
Conflicts with tidy packages ---------------------------------
combine():   dplyr, Hmisc  # loaded in my .Rprofile; also attaches gglot2
filter():    dplyr, stats
lag():       dplyr, stats
matches():   dplyr, sos   #from .Rprofile; doesn't seem to clobber findFn function
src():       dplyr, Hmisc
summarize(): dplyr, Hmisc
> cty0 = ggplot2::map_data("county")

Attaching package: ‘maps’

The following object is masked from ‘package:purrr’:

    map
