Thanks for all your help!! It actually has nothing to do with the environment variables. The issue is caused by the backup feature in Onedrive as Bill suggested. I do not know what magic trick Onedrive uses here but it misadvices R to use its directory, not my local Document directory. The answer might be from Windows FAQ question 2.14 like Duncan posted
After those two user-controllable settings, R tries to find system-defined home directories. It first tries to use the Windows "personal" directory This is confusing. First, this FAQ is not about how "R_USER" is defined. Instead, it talks about how we find the home directory from "R_USER". Second, it still did not answer what is "the Windows personal directory". I think this is where the issue is. My Document still has the path "C:\Users\wangj\Documents", but there is a backup path in "C:\Users\wangj\OneDrive\Documents". Unfortunately, R believes the latter one is the "personal directory". I hope this can be clarified a little bit to avoid confusion.
