解决Error in file(con, “w“) : cannot open the connection问题

今天打开电脑清理了下临时文件，然后运行原有无误的R代码发现运行报错了。
不难想到这和临时文件有关，因此假如出现

Error in file(con, "w") : cannot open the connection
In addition: Warning message:
In file(con, "w") :cannot open file 'C:\Users\27394\AppData\Local\Temp\Rtmps9VoVs\file32544f3527b': No such file or directory

或

Error in file(out, “wt“) : cannot open the connection

我们可以尝试使用以下代码重新生成临时存档就可以解决相关问题。

dir.create(tempdir())

相关解释是这样的
This happens when the temporary directory used by R is deleted. This usually happens when user or the system cleans up the tmp directory while the R session is running. Typically happens if the R session is open for a long time.
Remedy is very simple. You don’t actually need to restart R. Just re-create the temporary directory by:tempdir().
希望对大家有用~
