我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))
起初我遇到了一些错误&#34;&#39; GAJPCSR1_2003_2011.csvMapEnv&#39;不是来自&namespace; maps&#39;&#34;的导出对象。我重新安装了purrr
。错误消失了,一切正常!
我用其余的分析把它放回去,清理了我的环境,当R到达这个块时,同样的错误信息又回来了。
我已经获得了所有这些其他软件包,因此似乎其中一个软件包与purrr
不兼容。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。

您可以看到屏蔽或被屏蔽的所有内容
ResultSet
例如,在我目前的R会话中,您可以看到我已经回答了有关SO的问题,因为全球环境中的所有通用数据名称 conflicts(detail = TRUE)
,df
,和dt
屏蔽同名的基本功能。您可以看到数据表t
和first
屏蔽了last
版本,因为我在dplyr
之后加载了data.table
:
dplyr
