在 R 中获取 windows 系统文件夹（用户主目录、“我的文档”等）路径

Question

I would like to get the full path of user's home folder (usually something like C:\Users\%USERNAME%) or "My documents" folder and can't find the way to do this from R script. Is there any solution for this?

Answer 1

我想你想要：

path.expand('~')

Answer 2

使用包fs ，您还可以获得主目录：

library(fs)

path_home()

Answer 3

To get C:/Users/%USERNAME% without any extra package (or, with "base") you can use

Sys.getenv("USERPROFILE")

The path.expand('~') suggested above gave me the equivalent of C:/Users/%USERNAME%/Documents

obs: that worked for me in Win 10 and Win11 and with R3.4 and 4.1
