sys.setenv() 是否修改.Rprofile 或.Renviron？

Question

I have been reading about the differences between these files but can't find even in the Sys.setenv() documentation which of these files the function is intended to modify?

Answer 1

• You can use Sys.setenv() for modifying the .Rprofile file.
• You can use usethis::edit_r_environ() for modifying the .Renviron file.

There's a wealth of information in this RStudio blog page about the difference between the two.

Answer 2

according to this post , Sys.setenv() can also modify.Renviron so how do we specify which of the two it will modify?
