我怎么知道哪些包在干扰其他包？

Question

我正在使用以下代码将一些文件放在一起：

data_path <- "daymet"
files <- dir(data_path, pattern = "*.csv")

daymet <- data_frame(filename = files) %>% 
  mutate(file_contents = map(filename, ~ read_csv(file.path(data_path, .), 
    skip=7)))%>%
  unnest()%>%
  mutate(site = str_sub(filename, 1, 3))

起初我遇到了错误“'GAJPCSR1_2003_2011.csvMapEnv' 不是从 'namespace:maps' 导出的 object”的一些问题。我重新安装了 purrr。错误消失，一切正常！

我把它和我的其余分析一起放回去，清理了我的环境，当 R 到达这个块时，同样的错误消息又回来了。

我还有所有这些其他软件包，所以其中一个似乎不能很好地与 purrr 一起使用。或者可能不是。即使我没有加载所有包，我仍然会收到相同的错误消息。

您可以看到使用

屏蔽或被屏蔽的所有内容

 conflicts(detail = TRUE)

例如，在我当前的 R 会话中，您可以在下面看到我一直在回答有关 SO 的问题，因为全局环境中的所有通用数据名称，df、dt，和 t 屏蔽同名的基本函数。你可以看到数据 table 的 first 和 last 掩盖了 dplyr 版本，因为我在 dplyr:[=20 之后加载了 data.table =]

> conflicts(detail = T)
$.GlobalEnv
[1] "n"     "df"    "dt"    "gamma" "t"    

$`package:stringr`
[1] "%>%"

$`package:data.table`
[1] "between" "first"   "last"   

$`package:dplyr`
 [1] "%>%"       "between"   "first"     "last"      "n"         "filter"    "lag"      
 [8] "intersect" "setdiff"   "setequal"  "union"    

$`package:ggplot2`
[1] "Position"

$`package:stats`
[1] "df"     "dt"     "filter" "lag"   

$`package:methods`
[1] "body<-"    "kronecker"

$`package:base`
[1] "body<-"    "gamma"     "intersect" "kronecker" "Position"  "setdiff"   "setequal" 
[8] "t"         "union"

我怎么知道哪些包在干扰其他包？

How do I know which packages are interfering with the others?

r

purrr

tidyverse
