请假设该卷的编号为BOB,并在此附上一个文本文档:/Volumes/BOB/datarafter/data.txt

setwd("/Volumes/BOB/") # This works 
setwd("/Volumes/BOB/datafolder/") # This reverts to $HOME or ~ and doesn t go to the folder... 

因此,每当我试图指出一卷数据集时,我就告诉我:

Error in file(con, "r") : cannot open the connection
In addition: Warning message:
In file(con, "r") :
  cannot open file  /Volumes/BOB/datafolder/data.txt : Operation not permitted

我尝试把计算机主要驱动器的数据分门别类,并投入使用。 然而,数据非常庞大,无法把全部数据输入我的主要动力。 能够直接从外部硬性驱动器读取数据,将是一件难事。

如何通过<代码>RStudio做到这一点?

I found this question but not a compelling answer for this. R list.files(my_working_directory) shows no files but I know they are there. How to fix?

最佳回答

基本上,在试图获得关于另一条硬车的数据时,我注意到,马科斯要求我允许进入新的硬车。

我现在想到,运动的隐私或可及性存在问题。 因此,我参加了<代码>。 系统设置――> 隐私和安插; 安全――> RStudio。 随后在<代码>下,可移动量 我把它开了门(重新启动的RStudio),然后再次开门(重新启动RStudio)。 然后,我可以查阅档案!

希望是解决办法。 尽管我不清楚为什么它这样做了。
